%attrtest
Usage: attrtest

This command tests ECU's console attributes.  You can try it if
you like, but it is primarily for testing an ECU port.
#--------------------------------------------------------------------
%ax
Usage: ax [<param>]

<param> may be a single ASCII character, a standard ASCII identifier
(such as ETX), or a two-character control character identifier (such as
^C, typed as a caret followed by a C).

If no parameter is supplied, a table of control characters is printed
containing decimal, octal, hex, ASCII identifiers and two-character
control character identifier.
#--------------------------------------------------------------------
%xa
Usage: xa [<hex-val>]

<hex-val> is a hexadecimal value between 0 and FF; the parity (sign) bit
is stripped and the equivalent ASCII character value is displayed.

If no parameter is supplied, a table of control characters is printed
containing decimal, octal, hex, ASCII identifiers and two-character
control character identifier.
#--------------------------------------------------------------------
%oa
Usage: oa [<octal-val>]

<octal-val> is a octal value between 0 and 0377; the parity (sign) bit
is stripped and the equivalent ASCII character value is displayed.

If no parameter is supplied, a table of control characters is printed
containing decimal, octal, hex, ASCII identifiers and two-character
control character identifier.
#--------------------------------------------------------------------
%da
Usage: da [<decimal-val>]

<decimal-val> is a decimal value between 0 and 0377; the parity (sign)
bit is stripped and the equivalent ASCII character value is displayed.

If no parameter is supplied, a table of control characters is printed
containing decimal, octal, hex, ASCII identifiers and two-character
control character identifier.
#--------------------------------------------------------------------
%ansif
Usage: ansif [off | on | ]

This command displays or controls the state of the ECU ANSI filter.  If
on, ECU interprets the incoming bytestream as addressing an ANSI
terminal; the control sequences are detected and reissued to the local
console per its terminal database description.  In addition, a virtual
screen image is kept by ECU.

If off, the inciming bytestream is passed directly to the local console.
No virtual screen image is kept.
#--------------------------------------------------------------------
%autorz
Usage: autorz [ | off | on ]

This command displays or controls the state of the ECU autorz
switch. If on, an incoming ZMODEM preamble will automatically
start a ZMODEM receive operation.
 
ECU in the interactive mode (no procedure executing) can interpret a
SUB, 'B', '0', '0' receive data sequence as a ZMODEM ZRQINIT frame and
automatically begin a ZMODEM receive operation.  This command controls
or displays this feature.  By default, this feature is turned on.
#--------------------------------------------------------------------
%ayt
Usage: ayt

If your ECU is in telnet connection, this command sends the
AYT (Are You There?) command to the remote host.  If the
remote is sane (and so disposed), it will reply with something
like "[Yes]".
#--------------------------------------------------------------------
%baud
Usage: baud [<bit-rate>]

<bit-rate>, if specified, must be taken from the values 110, 300, 600,
1200, 2400, 4800, 9600, 19200 and 38400.  On some systems, 19200 and
38400 may not be supported.  If a bit rate less than 300 is selected, 2
stop bits are automatically specified; other bit rates set 1 stop bit.
If <bit-rate> is not supplied, the current bit rate is displayed.

The setting may be automatically changed as the result of a 'dial'
command.  See also the 'dial' and 'parity' command descriptions.
#--------------------------------------------------------------------
%bn
Usage: bn [ off | on | alert ]
.br
       bn [ 0 | 1 | 2 ]
.br

"bell notify": If no parameter is supplied, the current setting is
displayed.  Specifying 0 or off disables the facility; 1 or on causes
an audible alarm to be sounded upon receipt of a bell (0x07)
character from the remote system; 2 or alert causes an audible alarm
upon receipt of ANY characters.  This command may not be functional
in the version for your system.
#--------------------------------------------------------------------
%break
Usage: break

This command sends a break signal to the remote system.
On asynchronous ports this is done with a "long space disconnect."
On telnet, an Interrupt Process command is sent.
#--------------------------------------------------------------------
%cd
Usage: cd [<dir-path>]

This command allows you to change the working directory of the ECU
process.  If <dir-path> is supplied, the previous working directory is
displayed, and <dir-path> is made the new working directory.  A history
of previous directory changes is maintained.  Entering the 'cd' command
shows the numbered history list and allows you to select a new directory
by entering the number.  Other commands allow deletion of directories
from the list or saving the list to file ~/.ecu/dir.  This file is
automatically read at ECU startup, providing a convenient list of
directories available for quick selection.
#--------------------------------------------------------------------
%conxon
Usage: conxon [<arg>]
.br
where <arg> is on    honor ^S/^Q local flow control (DEFAULT)
.br
               off   pass ^S/^Q to remote
.br

This command enables or disables console xon/xoff flow control.
If the argument is omitted, the current flow control state is
displayed.  If on, typing ^S/^Q stops or restarts the local
console driver output.  If off, ^S and ^Q are passed to the
remote (for EMACS, of course -- who else?).
#--------------------------------------------------------------------
%dcdwatch
Usage: dcdwatch [<dcdwatch-param>]

This command controls the DCD watcher.  The optional parameter may be:
.br
   y  yes - enable DCD watcher
.br
   n  no - disable DCD watcher
.br
   t  terminate - terminate ECU on loss of DCD
.br
Entering the command without an argument shows the current status.

The DCD watcher when enabled causes ECU to monitor the DCD line (within
the limits imposed by the OS with its CLOCAL=0 functionality).  When the
watcher is on and DCD drops, ECU automatically performs the action of
the interactive or procedure hangup command.  If the 't'erminate option
is chosen, then after hangup processing is complete, the ECU program
will terminate.

The state of the watcher may be changed by the use of the dial command
which uses a directory entry that changes the DCD watcher status.  See
the manual sections on the interactive commands 'dcdwatch' and 'dial'.
#--------------------------------------------------------------------
%dial
Usage: dial [<dial-param>]

<dial-param> may take one of two forms, a telephone number to dial or a
logical name which can be found in the user phone directory (in file
~/.ecu/phone).

If a telephone number is supplied, the phone number is dialed;
you must first have set the desired bit rate and parity using
the 'baud' and 'parity' commands.  If a logical name is entered, the
phone directory is searched; if the entry is found, the bit rate
and parity is automatically set and the number dialed.

If <dial-param> is not supplied, then a screen-oriented
self-documenting directory manager is executed; you may scan the
directory to select a number to dial, as well as add, remove and
edit entries.  See also 'baud' and 'parity'.
#--------------------------------------------------------------------
%do
Usage: do <procname> [<arg> ... ]

Perform ECU procedure.  ECU searches for <procname>.ep in the current
directory.  If the file is not found, the program looks for the file in
the ~/.ecu directory.  One or more arguments may be passed to the
procedure.
#--------------------------------------------------------------------
%duplex
Usage: duplex [ Full | Half ]

This command specifies whether or not ECU is to locally echo characters
typed by you at the keyboard.  The overwhelming majority of remote
systems provide the echo function, in which case full duplex must be
used.  For the rare occasions when the remote system does not echo your
keyboard input, setting half duplex will allow you to see what you are
typing.

When communicating with another terminal in a "teletype conver-
sation", setting half duplex is generally required.  In such
cases, use of the 'nl', 'nlin' and 'nlout' commands may also be
required.

The default setting for duplex is full.
#--------------------------------------------------------------------
#%esc
#Usage esc <hex-constant>
#"command escape ": This command is used only on non-XENIX systems.
#It specifies the equivalent character for the HOME key used
#by XENIX versions of ECU to enter the commands being described
#by this help function.  The default setting for this command escape
#s '%'.  To change the value, you must enter the hexadecimal value
#of the desired character; it must be in the range 01 through 7F.
#You may use the 'ax' command to aid in converting an ASCII
#character to the appropriate hexadecimal value.
#--------------------------------------------------------------------
%fasi
Usage: fasi [reset]

This command displays or resets the FAS/i tty driver statistics.
The command is found only in versions compiled for FAS/i support.
#--------------------------------------------------------------------
%fi
Usage: fi [<filename>]

"file insert": This command causes file characters to be inserted into
the transmit data stream as though they had been entered at the
keyboard.  If <filename> is not entered on the command line, a prompt
for the filename is made.  Once the filename has been entered and file
has been opened, you are asked whether the file should be transmitted at
full speed, by "echo pacing" or by a single line at a time.  You may
also append an 'f', 'e' or 's' argument to the command line.  If your
remote can tolerate it, full speed transmission is the fastest.
Pressing the interrupt key (DEL) stops a full speed transmission.  By
specifying echo pacing, it is possible to increase the likelihood of
proper receipt.  Pressing the interrupt key (DEL) stops an echo paced
transmission.  As a last resort, if echo pacing is not working for you,
(i.e., you are using the command in an environment where the remote does
not echo your characters), use single line at a time transmission.  You
must press the space key to initiate sending each line.  Pressing 'ESC'
or 's' stops the transfer.
#--------------------------------------------------------------------
%fkey
Usage: fkey [<keyset_name>]

This command allows the mapping of function keys F1-F12, PgUp, PgDn, End
and Ins and the cursor up, down, left and right keys to emit a desired
sequence of characters when a function key is pressed.  <keyset_name>
specifies which key set in ~/.ecu/keys is to be selected: Sample entry
in ~/.ecu/keys:

hayes
.br
	F1:escape:+ + +
.br
	F2:autoans:A T S 0 = 1 cr
.br
	F3:dial:A T D T
.br
bbs
.br
	F1:cancel:^K
.br
	F2:yes:y cr
.br

If a keyset_name matches a logical dial directory name, it is loaded
when the number is dialed.
#--------------------------------------------------------------------
%fkmap
Usage: fkmap                           display current mapping
.br
       fkmap <keyname>                 display single key mapping
.br
       fkmap <keyname> <keylist>       modify a key's mapping
.br
       fkmap -l <name>
.br
       fkmap -r                        reset to original mapping
.br
       fkmap -s <file>                 append current to file
.br

This command manages the mechanism ECU uses to recognize function keys
when they are entered at the console.  If supplied, the first argument to
the command must be the recognized name of a function key from the list:

F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 Home End PgUp PgDn CUP CUL CU5 CUR CUD

If only one argument is supplied, the mapping for the specified key is
displayed.  If more than one argument is supplied, the keyboard mapping is
changed.  Arguments 2-n are character code specifiers in the format used
to define a funckeymap entry.

WARNING: If found to be syntactically correct, a mapping change is
installed immediately.  If incorrect mapping of the HOME key is requested,
you may lose control of ECU.

For a description of the other options, see the manual.
#--------------------------------------------------------------------
%hangup
Usage: hangup

This causes DTR to be momentarily interrupted, terminating any
outstanding connection.  Your DCE (modem) must be able to drop carrier
upon loss of DTR.
#--------------------------------------------------------------------
%help
Usage: help [<cmd-name>]

Issuing this command with no argument displays a list of commands
followed by a request for a command for further information.
#--------------------------------------------------------------------
%kbdtest
Usage: kbdtest

This command runs a keyboard test which asks you to press function keys
(e.g., F1).  For each key pressed, ECU gives you the actual character
sequence generated by the key.  It also tells you which function key it
recognizes (if any).  mapping of keyboard generated character sequences
to ECU internal key codes.  The command is useful for verifying and
debugging a "funckeymap" entry.  To exit the test at any time, press the
escape key.
#--------------------------------------------------------------------
%llp
Usage: llp

This command is a shorthand version of 'log /dev/lp'.
/dev/lp must not be under the control of a print spooler.
#--------------------------------------------------------------------
%loff
Usage: loff

This command is shorthand for 'log off'.  If session logging
is active, it is turned off.
#--------------------------------------------------------------------
%log
Usage: log [-s] [-r] [ | off | filename ]
.br
       -s "scratch" previous file contents; otherwise append
.br
       -r "raw" logging; otherwise non-printable characters
.br
          other than tab and newline are omitted from the log
.br

This command controls session logging; issuing the command with no
argument causes the status of session logging to be displayed.  The
special argument 'off' causes active logging to be terminated.  Other
argument values cause logging to start using the argument as a filename.
Issuing a 'log filename' command when logging is already active causes
the previous file to be closed and the new file to be opened.  Switches
are meaningful only when used in conjunction with a filename to start
logging.
#--------------------------------------------------------------------
%memstat
Usage: memstat

Experimental malloc display.  -lmalloc bug may report erroneous data.
#--------------------------------------------------------------------
%mkdir
Usage: mkdir <dirpath>

Create a new directory named <dirpath>.
#--------------------------------------------------------------------
%nl
Usage: nl

Display the current setting of CR/LF mapping.  For more information,
refer to the 'nlin' and 'nlout' command descriptions.
#--------------------------------------------------------------------
%nlin
Usage: nlin [<y-n>]

This command controls whether or not a newline (NL/LF) character is sent
to the screen upon receipt of a carriage return (CR) from the remote
system.  Most remote computers supply a NL after CR.  When communicating
with another terminal in a "teletype conversation", this is generally
not the case (see also the 'duplex' command).

Issuing the command without <y-n> causes the current setting to be
displayed.  The format of <y-n> is flexible: 'y' or '1' enables
appending NL to CR, 'n' or '0' causes the feature to be disabled.
#--------------------------------------------------------------------
%nlout
Usage: nlout [<y-n>]

This command controls whether or not a newline (NL/LF) character
is sent to the remote system upon transmission of a carriage
return (CR) entered by the keyboard.  Most remote computers do
not require (indeed "dislike") a NL after CR.  When communicating
with another terminal in a "teletype conversation", this is
generally not the case (see also the 'duplex' command).

Issuing the command without <y-n> causes the current setting to be
displayed.  The format of <y-n> is flexible: 'y' or '1' enables
appending NL to CR, 'n' or '0' causes the feature to be disabled.
#--------------------------------------------------------------------
%parity
Usage: parity [ None | Even | Odd ]

This command controls the parity of characters transmitted by the
keyboard.  Issuing the command with no parameter displays the current
setting.  When the parameter is supplied, only the first character is
required.  Even or odd parity implies seven data bits; no parity implies
eight data bits.  Parity of incoming characters is not checked.

The setting may be automatically changed as the result of a 'dial'
command.  See also the 'baud' and 'dial' command descriptions.
#--------------------------------------------------------------------
%pid
Usage: pid

This command displays the process id of the ECU transmitter process, the
ECU receiver process and the process ids of ECU's parent and group.
#--------------------------------------------------------------------
%ptrace
Usage: ptrace [ 0 | 1 | on | off]

This command controls whether or not procedure execution is to be
traced.
#--------------------------------------------------------------------
%pwd
Usage: pwd

This command prints the current working directory of the ECU process.
#--------------------------------------------------------------------
%rk
Usage: rk

This command searches the PATH list for 'ckermit' (Columbia University
C-Kermit) and invokes it to receive files.  See the ECU documentation
for modifications necessary to ckermit for ECU operation.  The file
~/.kermrc must be set up to have any desired initialization parameters
you desire.  Refer to C-Kermit documentation for more information.
#--------------------------------------------------------------------
%redial
Usage: redial [<retry-count> [<pause-interval>]]

This command redials a number previously dialed with the 'dial' command.
Modem status is tested and multiple retries may be made.  <retry-count>
specifies how many retries are to be made.  <pause-interval> specifies
how many seconds the program pauses after a failure to connect.  You
must specify <retry-count> in order to specify <pause-interval>.  The
default value for <retry-count> is 10. The default <pause-interval> is 60.

You should know that in some jurisdictions, it is ILLEGAL to dial the
same telephone number more than a specified number of times during some
interval of time.  In any case, specifying <pause-interval> less than 15
seconds is silently changed to 15 seconds.
#--------------------------------------------------------------------
%rev
Usage: rev

This command displays ECU's revision, the date and time ECU was
made and the status of CFG configuration switches used to make
ECU.
#--------------------------------------------------------------------
%rx
Usage: rx

This command invokes a modified version of Chuck Forsberg's rz program
(version 1.31) to receive files from the remote system using XMODEM/CRC.

After entering the command, you are prompted as to whether or not file
CR/LF characters are to be converted to newlines.  If you are
transferring text files from a system which contain CR/LF line
terminators, you must answer yes to this question.  You should answer no
when transferring binary files, such as executables, .arc files and the
like.  File transfer progress is presented on a visual display.  To
abort the transfer, press your interrupt key (usually DEL unless reset
with stty(C)).
#--------------------------------------------------------------------
%ry
Usage: ry

This command invokes a modified version of Chuck Forsberg's rz program
(version 1.31) to receive files from the remote system using YMODEM
batch with CRC-16 error correction.  The YMODEM is "true YMODEM", not
XMODEM-1k.  File transfer progress is presented on a visual display.  To
abort the transfer, press your interrupt key (usually DEL unless reset
with stty(C)).
#--------------------------------------------------------------------
%rz
Usage: rz

This command invokes a modified version of Chuck Forsberg's rz program
(version 1.44) to receive files from the remote system using
ZMODEM/CRC32.  File transfer progress is presented on a visual display.
To abort the transfer, press your interrupt key (usually DEL unless
reset with stty(C)).
#--------------------------------------------------------------------
%sk
Usage: sk [<file-list>]

This command searches the PATH list for 'ckermit' (Columbia University
C-Kermit) and invokes it to send files.  The file ~/.kermrc must be set
up to have any desired initialization parameters you desire.
Refer to the ECU manual and to C-Kermit documentation for more information.

After entering the command, you are prompted as to whether or not file
newline characters are to be converted to CR/LF.  If you are
transferring text files to a system which requires CR/LF line
terminators, you must answer yes to this question.  You should answer no
when transferring binary files, such as executables, .arc files and the
like.  You are prompted to enter a list of files to send, which may
contain one or more wildcard specifications.
#--------------------------------------------------------------------
%stat
Usage: stat

This command displays various status and statistics about ECU usage.
Its display varies from system to system and is generally
self-explanatory.

#--------------------------------------------------------------------
%sx
Usage: sx [<file-name>]

This command invokes a modified version of Chuck Forsberg's sz program
(version 1.44) to send a file to the remote system using XMODEM/CRC.

After entering the command, you are prompted as to whether or not file
CR/LF characters are to be converted to newlines.  If you are
transferring text files from a system which contain CR/LF line termi-
nators, you must answer yes to this question.  You should answer no when
transferring binary files, such as executables, .arc files and the like.

You are prompted to enter a filename to send.  File transfer progress is
presented on a visual display.  To abort the transfer, press your
interrupt key (usually DEL unless reset with stty(C)).
#--------------------------------------------------------------------
%sy
Usage: sy [<file-list>]

This command invokes a modified version of Chuck Forsberg's sz program
(version 1.44) to send file(s) to the remote system using YMODEM/CRC.

You are prompted to enter filename(s) to send, which may consist of one
or more wildcard specifications.  File transfer progress is presented on
a visual display.  To abort the transfer, press your interrupt key
(usually DEL unless reset with stty(C)).
#--------------------------------------------------------------------
%sz
Usage: sz [<file-list>]

This command invokes a modified version of Chuck Forsberg's sz program
(version 1.44) to send file(s) to the remote system using ZMODEM/CRC32.

You are prompted to enter filename(s) to send, which may consist of one
or more wildcard specifications.  File transfer progress is presented on
a visual display.  To abort the transfer, press your interrupt key
(usually DEL unless reset with stty(C)).

Note: if you specify sending only newer files and the remote receiver
does not support the feature, it may skip (reject) all your files.
Retry the transfer specifying 'N' to 'Transfer only newer files'.
#--------------------------------------------------------------------
%time
Usage: time

This command displays the local date and time as well as the current UTC.
#--------------------------------------------------------------------
%tty
Usage: tty

This command displays the current console tty name.
#--------------------------------------------------------------------
%erto
Usage: erto [<msec>]

This command specifies the default timeout period (in milliseconds)
of the next "expect" in an ECU-executed expect-respond script.
Remember that ECU expect-respond scripts can change timeouts on their
own, so this number may not "stick." Entering the command with no
arguments displays the current value (which, again, may not be the
value ECU started with or the value you last selected).
#--------------------------------------------------------------------
%erverbose
Usage: erverbose [<true-false>]

This command specifies the verbosity level of an ECU-executed
expect-respond script.  Entering the command with no argument
displays the current status of verbosity. To change the value, enter
an argument beginning with an lower-case 'y' or 'n'.

Examples:
.br
    erv
.br
    erv y
.br
#--------------------------------------------------------------------
%exit
Usage: exit

This command terminates ECU promptly.  If your modem does not
drop carrier upon loss of Data Terminal Ready (DTR), you must use
the 'hangup' command prior to issuing the 'exit' command.  It is
strongly recommended that you configure your modem to hang up the
phone line when DTR drops.  A shorthand version of this command
exists: '.' is equivalent to 'exit'.
#--------------------------------------------------------------------
%xon
Usage: xon [<arg>]
.br
where <arg> is on    input and output flow control
.br
               off   no flow control
.br
               in    input flow control
.br
               out   output flow control
.br

This command enables or disables xon/xoff flow control.  If the
argument is omitted, the current flow control state is displayed.
#--------------------------------------------------------------------
%!
Usage: !
.br
       !<command>
.br

The '!' command is a shell escape.  The environment variable SHELL is
read to determine what shell program to execute (e.g., /bin/sh, etc).
If '!' is entered by itself, an interactive shell is started; press ^D
to exit back to ECU.  If <command> is supplied, it is executed by the
shell with an immediate return to ECU.

Similarly,
.br
  '$' causes the communications line to be stdin and stdout
.br
      for the spawned shell
.br
  '-' is similar to '>', except the command is executed directly
.br
      without going through a shell.
.br
#--------------------------------------------------------------------
%$
Usage: $
.br
       $<command>
.br

The '$' command is a shell escape causing the communications line
to be the standard input and output.  The environment variable
SHELL is read to determine what shell program to execute (e.g.,
/bin/sh, etc).  If '$' is entered by itself, an interactive shell
is started; a ^D received from the communications line causes the
shell to terminate and control to be passed back to ECU.  If
<command> is supplied, it is executed by the shell with an
immediate return to ECU.
#--------------------------------------------------------------------
%-
Usage: -<command>

The '-' command causes <command> to be executed directly without
passing through a shell (no wildcard expansion or other shell
processing occurs).  Standard input, output and error all are
opened to the console.  In addition, all other files (including
the communications line) opened by ECU remain open.
#--------------------------------------------------------------------
%?
Usage: ?

This is an alias for the help command.
#--------------------------------------------------------------------
%clrx
Usage: clrx

The 'clrx' command simulates receipt of an XON by ECU.  It is useful
in the rare circumstances that an XOFF is received by ECU from a 
remote system and no later XON is received.
#--------------------------------------------------------------------
%pcmd
Usage: pcmd <procedure command>

The 'pcmd' command allows a procedure command to be issued from the
interactive command prompt.  It is primarily intended for debugging
procedure commands, but it is available for any use.  Certain
commands are illogical from the interactive mode.  Attempting, for
instance to execute a `whilei' will result in the error `not executing
a procedure.'
#--------------------------------------------------------------------
%plog
Usage: plog [<filename> | off | ]

The 'plog' command turns on or off procedure logging.  If the
argument to the command is 'off', logging is turned off, otherwise
logging is started on the specified file.  If no argument is specified,
the status of procedure logging is displayed.
#--------------------------------------------------------------------
%rtscts
usage: rtscts [ off | on | no | yes | 0..7 ]

This command turns on or off the driver RTS and CTS flow control if
support is provided by the OS. This is a complex subject
and you should refer to the manual and the UNIX oral/net
tradition if you are confused.

For SCO:
.br
argument | RTSFLOW | CTSFLOW   argument | RTSFLOW | CTSFLOW | CRTSFL
.br
---------+---------+---------  ---------+---------+---------+--------
.br
  off    |   0     |   0         0      |   0     |   0     |
.br
  on     |   0     |   1         1      |   0     |   1     |
.br
  no     |   0     |   0         2      |   1     |   0     |
.br
  yes    |   0     |   1         3      |   1     |   1     |
.br
                                 4      |   0     |   0     |   1

Choice 4 only works on SCO 3.2v4 and ODT 2.0.  As you can see, numeric
values are masks.  If the 4 bit is present in the numeric value, it
overrides the lower-order bits: Specifying 7 as an argument specifies
CRTSFL is to be used if it is supported, otherwise RTSFLOW and CTSFLOW.

A similar feature is provided under SVR4 and SunOS.  See the ECU manual
and your system's termio man page (termios for SunOS) for details.
#--------------------------------------------------------------------
%sdname
Usage: sdname [<filename> | ]

This command sets or displays the current screen dump filename.
Until the command is issued, screen dump data is placed in
~/.ecu/screen.dump.
#--------------------------------------------------------------------
%sgr
Usage: sgr mode cmd

This experimental command is used to test the timed read primitive
used by ECU.  The command <cmd> is sent to the line and a timed read
is performed.  The data returned is displayed in hexadecimal format on
the console.  The stimulus (cmd) and response is logged in
./ecu.sgr.log if the current directory must be writable.  Refer to
source module ecugrabbag.c function send_get_response() for details.
See SGRTO1 and SGRTO2 for additional flexibility
#--------------------------------------------------------------------
%sgrto1
Usage: sgrto1 <msec>

Set time to wait for first character in response to an sgr stimulus.
#--------------------------------------------------------------------
%sgrto2
Usage: sgrto2 <msec>

Set time to wait for later characters in response to an sgr stimulus.
#--------------------------------------------------------------------
%td
Usage: td

Display the termcap strings that ECU received from termcap
initialization. Useful for debugging screen display problems.
#--------------------------------------------------------------------
%telopt
Usage: telopt [ y | n | ]

If configured for it, ECU can make internet (telnet) connections.
When in one, telnet options are exchanged between ECU and the
remote telnetd.  This command controls or displays whether or not
ECU displays visible evidence of such traffic.  By default, this
feature is turned off.

There is little traffic once the session begins.  You most likely
wish to use the -z switch or use the procedure version of this
command in an _rc.ep file.
#--------------------------------------------------------------------
%ts
Usage: ts

This experimental command displays raw termio structure information
for the console and the tty.  It is primarily used in debugging ECU.
#--------------------------------------------------------------------
%xlog
Usage: xlog [y | n]

This experimental command controls exhaustive logging by the X, Y, and
ZMODEM file transfer protocols to files named /tmp/szNNNNN.log or
/tmp/rzNNNNN.log where NNNNN is the process id of the transfer process.
#--------------------------------------------------------------------
%eto
Usage: eto [msec]

This experimental command sets or displays the "escape timeout"
for non-multiscreen function key detection.  Use caution: although
the command has a lower limit, you may set the value low enough
not to be able to use the HOME key!
#--------------------------------------------------------------------
%nice
Usage: nice [niceval]

This command sets or displays the process nice value.  The usual
rules apply (hint: you might accidently nice4 yourself into not
getting enough CPU!)
#--------------------------------------------------------------------
%pushd
Usage: pushd [ | <dir> ]

This command either 1) pushes the current directory pathname onto
a stack and establishes a new directory or 2) shows the current
stack.  Issuing the command with no argument displays the stack.
#--------------------------------------------------------------------
%popd
Usage: pushd [ | <#> | all ]

This command pops one, many or all of the entries off directory
stack, restoring a previous directory.  No argument results in
one directory being popped.  A numeric argument pops the stack to
a specified level.  'all' is equal to the numeric value 0 (and
may be abbreviasted 'a').
