- ============= Changes for ECU 3.20 =======================================
- last revised Sat Aug 22 15:29:11 EDT 1992
- "But in our enthusiasm, we could not resist a radical overhaul of
- the system, in which all of its major weaknesses have been
- exposed, analyzed, and replaced with new weaknesses." -- Bruce
- Leverett 'Register Allocation in Optimizing Compilers'
- 1. new commands (procedure and interactive)
- a. autorz
- b. dcdwatch
- 2. dial command reworked
- a. new sub menu for entry add/edit
- b. phone number size increased from 25 to 40 characters
- (some modems limit input string size to 40 characters total
- excluding AT and trailing CR)
- c. Trailing dollar sign '$' appends ~/.ecu/.credit to dialled number:
- .credit has:
- ,,,167167002
- Home dial 1234 sends to modem
- 1234,,,167167002
- 3. help cmd improved: you can stay in a category and ask
- for help with multiple commands and use F1 to return to
- category menu.
- 4. Major rework inside to reduce but not eliminate the likelihood
- the chances ecu will abnormally terminate when the dial command
- needs to change to a new line and the new line is not available.
- If the new line is busy (in use by another dialout or login),
- the request to change is rejected and the old line is retained,
- the program survives. If the new line is unavailable because
- of other reasons (read/write denied [chmod] for instance), ecu still
- dies. hopefuly this will all be handled by the time of release.
- 5. jhpb@sarto.budd-lake.nj.us added preliminary support for ESIX SVR4
- and I added the necessary switches to config.c. Now, -DISCSVR4
- is used for ISCSVR4, -DESIXSVR4 for ESIX and -DSVR4 for "any" SVR4.
- 6. The "kbdtest" interactive command has been cleaned up enough
- for general use. I hacked it in for debugging early on.
- Now it is documented well enough for general use in funckeymap debugging.
- 7. -P command line switch added for selecting a phone directory other
- than the default ~/.ecu/phone. Use -P fullpath.
- 8. Any usage error (bad command args) resulted in the death of ecu's
- process group. This provided great incentive to invoke the program
- properly, but in this modern day, you are not allowed to discipline
- the students :-).
- 9. An experimental feature has been added to ecuungetty.
- If it is compiled with -DECUUNGETTY_CHOWN, it will perform
- chown and chmod operations on the line.
- When the line is acquired, its ownership is set to the real uid
- of the ecu user, its group id to the group id of the process, and
- its mode to 622. This is what happens to xterm ptys.
- When the line is released, its ownership is set to uucp
- of the ecu user, its group id to uucp, and its mode to 640.
- This is what SCO uugetty does when it starts on a line.
- You can experiment with this feature by
- a. placing the line
- LOCAL_CFLAGS = -DECUUNGETTY_CHOWN
- in the file `config.local' in the distribution base directory.
- b. Configure or ./config
- c. remake and reinstall
- *You* must decide if this is appropriate for you. The tradeoff
- is between having 666 ttys and having a program which a diligent
- hacker could use to change any file in the system to his
- ownership. You really should look at bamboozle.c and judge
- what level of protection you want to use. If you are on
- a sensitive installation (like you .gov or .mil guys),
- you might not want to do it. Any suggestions for improvement
- or additional security. I thought about pathname checking,
- st_dev and st_rdev checking and the like, but nothing simple
- and portable has come to mind.
- 10. From 31840 patch 5,
- By the time ECU actually attempts an line open, enough previous
- context has been lost that the program cannot recover if the open
- fails. I have always made several checks to try and eliminate
- such occurrences. Now, at least for SCO lines in utmp, the
- chances of failure are virtually eliminated.
- This patch goes with patch 4 to extend the benefits of ecuungetty
- chown. If ecuungetty chown is enabled and this patch is
- installed, we get reduced likelihood of ecu terminating
- abnormally when switching comm lines or when selecting the first
- line of the session.
- Line access is checked if it is not found in utmp to see if
- an open would fail.
- SCO uugetty does not always put anything in the ut_line field
- of its utmp entry. However, a de facto convention exists for
- making an inittab id field with the last two characters
- matching the last two characters (the only unique characters)
- of SCO-style comm line names. This patch causes such a check
- to be made, increasing the likelihood of getting a utmp match
- Two new files have been added to this distribution:
- dutmp.c cc -o dutmp dutmp.c dumps the utmp; a cheap who -a
- README.3.2v4 a brief blurb related to EAFS file names
- ecu 3.19.00 patch 1 - notes 11-15
- 11. The maximum screen geometry is now 85x80 instead of 43x80.
- Columns must be 80. Lines must be > 20. Lines
- in excess of 85 will be accepted, but ECU will be unable to
- maintain a correct screen display if any scrolling occurs.
- 12. A Nap() bug (used by the procedure nap command as well as
- internal functions) could cause the program to hang if napping
- was to occur when a receiver or child process terminated. This
- only occurred on systems with -DWORKING_SELECT: SunOS, the SVR4s,
- ISC 2.2, for instance.
- 13. Remaining program identifiers containing the string "nonansi.*key"
- were renamed to use "funckeymap".
- 14. On systems with reliable predefines in their native compiler,
- (SCO -DM_SYSV, SunOS -Dsun), Configure guesses at a default answer
- for the first question.
- 15. The End key may now be used to finish adding or editing
- a dialing directory entry.
- ecu 3.19.00 patch 2 - notes 16 - 18
- 16. Yet more work on the ecuungetty scheme. ungetty acquisition
- not attempted early enough for "enabled but idle" lines
- 17. A few patches back, I forgot to note %conn will now return
- -1 if no line is open. Previously it returned 0 in this case.
- Now -1 means no line open, 0 means line open but no connection,
- >0 is the line file descriptor for the line in an active
- connection.
- 18. The Nap() fixes of the last patch prevented ecurz/ecusz/ecusea
- from compiling. Sorry.
- From full release 3.19.05
- 19. A preliminary T3000 dialer has been added to the gendial
- package. This modem's future is plastic and the dialer, like
- all gendial programs, is just a starting point. Gendial is
- provided and I don't have a lot of time to support the zillions
- of conflicting idiosyncratic options folks want. With that
- spew spewed, most of them work fairly well. Documentation :-) ?
- 20. A side effect of getting the T3000 was that *I* got to play
- with ECU on a Sun. This is quite fortunate, since ECU was purportedly
- ported many CPU cycles ago. The Nap() problem has finally been
- put to bed... (he said).
- From 3.19.05 patch 1 (making 3.19.06) notes 21-24
- 21. The lCLOCAL() code and its users form the chassis upon
- which the DCD watcher is based. It appeared to work on the
- SCO box, but caused problems on SunOS that were difficult to
- find. Thanks to Mark Ashton, n4hgf!ifsbd!cma, this problem
- is history. Many mysterious "hangs" came from a trap
- you could fall into on *any* implimentation other than SCO UNIX.
- CLOCAL doesn't appear to work the same on SCO 3.2.? as XENIX
- and SunOS. I think tbetz@upaya.panix.com will be happy
- with this news.
- 22. cma also discovered that if you have multiple Devices entries
- for a line to pick up specific Dialers scripts or dialer programs,
- say:
- ACU ttya - 2400 t3000-2400
- ACU ttya - 9600 t3000-v32
- ECU would always pick the first one (disregarding baud rate).
- This is fixed now.
- Now, if you dial with a directory entry using a /Devices-type or
- =devices-type specification for tty, then *that specific* Devices
- entry is used to choose the dialer program or Dialers script. If
- no directory entry is involved or the directory entry specifies
- "Any" or a specific line, then Devices is searched for the first
- entry matching both the current line and the current baud rate.
- A note aside: SCO Devices entries appear to me to have a syntax
- extension not found in all HDB systems. The baud rate
- field allows a range of baud rates, like:
- ACU tty1A - 110-2400 /usr/lib/uucp/dialgHA24
- ECU supports this syntax, but your uucico may not.
- 23. models/funckeymap updated with my dual-purpose Sun/SCO
- funckeymap/.Xdefaults configuration.
- 24. cmostime4 has been included for SCO users (and many hackers)
- From 3.19.05 patch 2 (making 3.19.07) notes 25
- 25. Dialing directory subform data entry formerly had two
- input schemes: on input, you were cajoled into going through
- fields one at a time until you reached the end of the form, whereupon
- ECU would take away the input form. On the other hand, when editing
- an entry, you were free to cycle through the fields "a la modulo"
- in either direction.
- Now, both input modes allow liberal cycling. Pressing the END key
- signals your acceptance of the entry. Pressing ESCape in input
- mode aborts the new entry process. Pressing ESCape in edit mode
- behaves exactly like the END key except that any edits made since
- the cursor entered the current field are discarded..
- From 3.19.10 - notes 26-27
- 26. more internal cleanup
- 27. robertle@sco.com (Robert Lewis) noted that putting the phone number
- on log files and screen dumps is a security risk. Why protect
- ~/.ecu when the phone numbers are plastered everywhere. No
- more banners.
- From 3.19.11 - whoops didn't keep track
- 28. ecuungetty chown fixes and miscellaneous cleanup
- From 3.19.12 - notes 29
- 29. Added use of ECUFUNCKEY environment variable to override TERM
- when loading funckeymap.
- 3.19.13 internal rev (just superstitious :->)
- 3.19.14 - notes 30
- 30. Made changes for SCO 3.2v4/ODT 2.0:
- a. pids are now shorts
- b. getty sets "DIALOUT" on its own
- 3.19.15 - notes 31
- 31. ECUUNGETTY_CHOWN now a semi-permanent feature. It can
- still be turned off by editing config.c or Makefiles. It
- is just too good not to have it in.
- 3.19.16 - notes 32-37
- 32. cmostime4 backed out of distribution; if you want it, ask me
- 33. Direct phone numbers longer than 10 characters got doubled in
- one instance. Thanks to felton!rll for pointing this out.
- 34. Good news! -DWORKING_SELECT can be and is now used for
- 3.2v4; as a side effect, the Nap() wrapper/surrogate is now in
- nap.c and all the several Nap() functions in ecusea.c, zcommon.c
- and gendial.c have been removed.
- Also, if -DWORKING_SELECT is used, Nap() uses ftime() instead of
- gettimeofday(). Adding -DUSE_GETTIMEOFDAY will return to the
- old usage. This latter note is for porters, since all currently
- supported systems have ftime() and several lack gettimeofday().
- 35. More work has been done on SCO utmp/Devices automatic tty selection
- has been done. I apologize for the long chain of half-fixes. Once
- again, I think it is fixed. This time I REALLY believe it :-).
- For sure, you should no longer find your /dev/tty chown()'d to uucp.
- 36. SCO multiscreen color escape sequences from the remote were
- being filtered as if ECU were running on a non-multiscreen. Now,
- if you use ECU on an SCO multiscreen, the full set of ECU escape
- sequences, including color, again work as specified in the
- manual. Thanks to tps@jptcs.com for pointing this out. This bug
- crept in when I reorganized keyboard management
- (nonansikeys->funckeymap).
- 37. The ecuungetty chown feature is on permanently. I added
- quite a few security/safety checks to make sure some bug or
- another will not make the privileged ecuungetty go wild.
- 3.19.17 - notes 38
- 38. The hz/hzmsec needed by nap.c was not being provided,
- calculated by ecusea.c, ecu[rs]z.c and gendial.c.
- 3.19.18 - notes 39
- 39. I had started using <sys/time.h> if 3.2v4. 3.2v4 only has
- <sys/time.h> if the TCPRT package is installed . Basic 3.2v4 does
- not have it at all. So, we'll use <time.h> and <sys/select.h> just
- like before. Thanks for the report go to robertle@sco.com.
- 3.19.19 - notes 40-44
- 40. Added support for 3.2v4 CRTSFL.
- Now for SCO, rtscts command arguments:
- usage: rtscts [ off | on | no | yes | 0..7 ]
- argument | RTSFLOW | CTSFLOW argument | RTSFLOW | CTSFLOW | CRTSFL
- ---------+---------+--------- ---------+---------+---------+--------
- off | 0 | 0 0 | 0 | 0 |
- on | 0 | 1 1 | 0 | 1 |
- no | 0 | 0 2 | 1 | 0 |
- yes | 0 | 1 3 | 1 | 1 |
- 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.
- The interactive help and iteractive and procedure command
- documentation has been updated. I added to README.RTSCTS
- some illuminating comments by chip@tct.com (Chip Salzenberg).
- It was seeing this article that brought CRTSFL off the todo
- list and into the code.
- 41. Warnings about not using ^\Z in Kermit transfers (^Z suspend)
- were added to the 'sk' and 'rk' interactive and procedure commands.
- 42. This fix went into 3.19.16 but I forgot to note it: color
- sequences sent to ECU on a multiscreen console were not being
- passed to the driver. Now they are.. I only know of color
- working on SCO.
- 43. Changes to make_dirs() was needed to handle making
- directories with pathname components which are symbolic links
- (possibly on a read-only file system).
- 44. The DCD watcher did not work if you use SCO sio. I have
- been using FAS and forgot a a fact about SCO sio: to toggle
- CLOCAL meaningfully, you must open the modem (e.g. tty2B) rather
- than the direct (tty2b) file. On SCO systems, if the tty filename
- has a digit+letter as the last two characters, ECU will
- force the lower case (direct) version to be used. 3.19.19 opens
- the upper case (modem) device, but continues to store
- and display tty names in their lower case version.
- 3.19.20 - notes 45-46
- 45. Somewhere in the lifetime of .19, I sent a copy to a guy.
- This revision bump is just to keep from having different
- versions called .19 out the door.
- 46. On 3.19.17/18, there were various reports of hangs on line
- close, hang up, or HOME prompt when using 3.2v2. I cannot
- reproduce any of these errors. Please get and send me this
- information for me the next time it happens to you:
- Install ecu, but execute the ecu built in the distribution directory.
- a. Is the receiver process active (two ecu processes active)?
- b. The ecu transmitter process will either be the only ecu
- process or the oldest. Kill -4 the transmitter process and move
- the core file to the distribution directory if you 'cd'ed in ecu.
- You may have to type ^Jstty sane^J on the console it failed on
- (expect no echo) to restore the console to something usable. This
- may not reinstate your choice of character delete, line kill, etc.
- c. do 'sdb ecu |& tee sdb.log'
- d. do 't', then 'q'
- e. repeat the failing scenario if you found the receiver process
- alive in step a. If so, repeat a-d above, but this time kill
- the receiver process and do 'sdb ecu |& tee -a sdb.log'
- f. Guess. (mail me the sdb.log) with a description of
- 1) the OS
- 2) any non-vendor serial driver
- 3) what was going on when it failed (in 100 words or more :-> )
- 3.19.21 - notes 47-49
- 47. The UNIX sio driver may generate a SIGTTOU upon execution of
- certain ioctl() functions, namely, XCSETA, XCSETAF, XCSETAW,
- TIOCSPGRP, TCSBRK, TCFLSH, and TCXONC. My ignorance caused the
- last few revisions to hang for many upon closing a line or upon
- performing miscellaneous operations like sending a break. All
- ecu executables now set job control signals to SIG_IGN. I hope
- this fixes the problem. (Job control is not supported at this
- time.)
- 48. config.c has been returned to normal compilation (no -g).
- I shipped an alternate config.c "out of turn" after 3.19.20.
- Some may have installed it, some not. Therefore, unsharing
- this patch replaces any config.c you may have in place.
- 49. The -F switch was added to the command line arguments:
- The new manual section titled "-F path":
- Normally, the $TERM environment variable is used to
- determine the funckeymap entry (keyboard configuration)
- to be used. Sometimes, the $TERM variable is not
- adequate for identifying your keyboard arrangement.
- The -F switch, like the $ECUFUNCKEY environment
- variable, allows you to use override the funckeymap
- entry used. For more information, see the section
- titled "Function Key Mapping (Recognition)".
- 3.19.22 - notes 50-52
- 50. This note is only of interest to SCO users.
- Previous revisions of SCO were lenient on the user in the choice
- of the direct or modem tty device. You could specify either
- type and ecu would force the one it thought appropriate.
- Users of ecu under other operating systems have always had to
- specify the correct name.
- If you have time, I'd love feedback on what part of the manuals
- I have missed updating with the new paradigm.
- Since there are several types of async drivers and we want
- to support them, ecu can no longer make a choice for you.
- I did radical surgery on the "SCO tty naming" logic. As it
- stands nowu, on SCO, the tty you specify in a dialing entry is the exact
- tty name opened. The convention of using a lower-case lock name
- is still observed. Also, both senses are searched for in utmp
- for conflict determination. ecuungetty chown()/chmod() both
- device file names.
- However, your choice of which line type (line placed in tty field
- of a directory entry or the tty field of the setup form) depends
- upon the driver you are using:
- sio modem /dev/tty1A
- fas direct /dev/tty1a
- I don't know about others. Tell me.
- Notes:
- a. An sio direct line ignores setting of CLOCAL (no DCD watcher)
- and lacks support for hardware flow control.
- b. Opening the fas modem line causes various forms of conflict
- resulting in EBUSY being returned by fas for an ecu open or
- a dialer program open.
- For now, this is meaningful only on SCO. In the future, perhaps,
- we'll manage an installation-dependent table of what line names
- refer to the same device and which are modem, direct, etc.
- e.g.,
- #line_to_use:modem:direct:others:comment
- tty1A:tty1A:tty1a::sio
- tty1a:tty1A:tty1a::fas
- acu0:acu0:ttya,ttyd0:SunOs
- This would re-automate SCO tty line type choices and add it anew
- for others. Then, ecu could for the first time on non-SCO (and
- SCO naming to boot) search for all possible lock files and utmp
- entries. What do you think? Yes, one more damn configuration file
- to hack on.
- 51. ecusz, ecurz and ecusea are now placed in the ecu library directory
- (usually /usr/locsal/lib/ecu). This is a more appropriate place
- since it is meaningful only for ecu to execute them. Kermit or ckermit
- is still searched for through $PATH. Remove any old ecurz, ecusz
- and ecusea executables from your locsl bin directory.
- 52. I'm sorry the preformatted manuals you have been getting
- were malformed. The new Makefile in doc failed to supply -mm !
- BETA 3.20.01 notes 53-58
- 53. There is still one installation where /dev/tty is getting
- incorrectly chown/chmoded. There are now three brute-force
- tests for an attempt at this (up from two). The bug
- hasn't been fixed, but we ought to know how it happens
- this time around.
- 54. The procedure and interactive command fkmap has been added:
- Usage: fkmap display current mapping
- fkmap <keyname> display single key mapping
- fkmap <keyname> <keylist> modify a key's mapping
- fkmap -r reset to original mapping
- fkmap -s <file> append current to file
- 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.
- Examples:
- fkmap f10 display F10 mapping
- fkmap Home ^Z map Home to ^Z
- after this command, type ^Z for Home
- 55. Non-SCO color appears broken and it is beyond me to fix it.
- If you want to diddle with it, look at the top of ecutty.c at the
- list of conditionals regarding USE_COLOR. I'd appreciate
- patches. BTW, in the past, I have attempted fixes for ISC
- character attributes like underlining and standout, but I've
- never heard back. Are there attribute problems on ISC (3.2 or
- other)?
- 56. The procedure command exec was added:
- usage: exec <string>
- This function executes a string as a procedure statement.
- Argument <string> must contain an ecu statement exactly as
- might appear on a procedure line, with a few exceptions.
- 1. There may be no label: the first command may
- start in column one.
- 2. You should not execute a goto, gosub or return.
- 3. You should not code if, while or compound statement
- brackets.
- You are on your honor with regard to items 2 and 3 above.
- If you stretch it, it will break.
- Example:
- $s20 = 'Home'; $s30 = '^H'
- $s21 = 'End'; $s31 = '^E'
- $s22 = 'F1'; $s32 = '^A'
- $s23 = 'F2'; $s33 = '^B'
- $i10 = 0
- whilei $i0 < 4
- {
- $s0 = 'fkmap '+$s[20+$i10]+' '+$s[30+$i10]
- exec $s0
- $i10 = $i10 + 1
- }
- 57. ECU has been made successfully with gcc 2.2.2. There is a
- bug in the configure procedure in the 2.2.2 I received. In
- attempting to configure for 3.2v4, the tm.h header file got
- linked to the wrong file. Make sure tm.h is linked to
- config/i386_sco4.h and not config/i386_sco.h. Starting with
- 2.2.2, those nice M_ identifiers are predefined by gcc. I wish
- everybody's compiler had a predefine that would identify the
- environment.
- The Configure procedure is unchanged. Answer yes to the question
- about version 1.40 or later.
- 58. John Dashner, wa4cyb!jmd, proofread the main manual (THANKS). His
- changes are in the manual.
- FINAL 3.20 notes 59-65
- 59. Expect/respond \M and \m implimented for SVR4. The old \m
- millisecond delay is now ~n[##]. See the procedure manual in the
- description of the expresp command.
- 60. Further bugs with managing line chown/chmod fixed.
- A directly specified line not managed by getty was not getting
- chowned back to uucp when the line was closed.
- 61. Better syntax checking is done when reading Devices lines.
- 62. A bug in ecusz caused data transfer rate calculations to be
- wrong after any receiver ZRPOS ("nak") after the first one at
- transfer startup.
- 63. A "Resume interrupted transfer" choice has been added
- to the interactive sz menu. An equivalent -r switch was added
- to the sz procedure command. Previously, you had to "just know"
- you can sneak switches to the file transfer protocols by
- prefixing them to the file list.
- There is still no clean way for the sz procedure command to set
- the ZMODEM window size on sends other than the aforementioned
- trick. The thing to do here is
- sz '-w 65536 file1 file2'
- There is no foreseeable reason this hack will cease to work.
- However, if I get 1.0001 requests, and I'll come up with something
- better.
- 64. The receiver process was being started too soon after a
- connect resulting for a directory entry dial. As a result,
- if ther remote began transmitting very soon after connect
- or if there was remaining modem dialog remaining bufferred
- in the tty driver, the CONNECT or [interactive mode] messsages
- could have been intermixed with data from the line.
- This longstanding nuisance bug has finally been fixed.
- 65. The rtscts procedure command would take only on/off/yes/no
- alphabetic arguments. Now it will accept numeric arguments
- like its interactive equivalent.

- ==> Patch 1
- 1992-09-14-04:05-hdbintf.c-wht@n4hgf-rcvr process was not going away reliably
- 1992-09-13-12:52-ecutty.c-wht@n4hgf-add tty_is_scoterm
- 1992-09-13-12:52-ecuicmd.c-wht@n4hgf-show tty_is_scoterm during stat
- 1992-09-13-12:52-ecu.h-wht@n4hgf-add tty_is_scoterm
- 1992-09-13-02:05-ecuicmhist.c-wht@n4hgf-redisplay escape prompt on error exit
- ALERT: Something is happening to make ODT 2.0 scoterms go CPU
- open-loop and unresponsive to anything but a kill -9. I will be
- looking into this, but if anyone beats me to it, please let me
- know what you find ASAP. Thanks.
- 1. The receiver process was not being killed during dialing when
- ECU was invoked with "ecu directoryentry". Dialing was not
- possible until you interrupted the program and tried again. This
- has been fixed. This boo-boo crept as part of some cleanup work
- (smile) just before posting.
- 2. An <scoterm> indication has been added to the stat command
- output. This is a start on the debugging effort of the scoterm
- problem that had to be put off for the critical nature of item 1.
- 3. After the history function displays "no interactive commands
- saved", you are still in command mode. There was no visual hint
- to let you know that. Then you could type, thinking you were
- sending to a remote, when in fact you were feeding the text to
- the command line. Now, ECU redisplays the escape prompt to show
- you are still in command mode.
- 4. Typos in the README and README 3.20 were fixed.
- 5. This file was added.
- ==> Patch 2
- 1992-09-15-18:52-ecutty.c-wht@n4hgf-left some debug code in patch01 dammit
- 6. Remove debug code from _setcolor().
- ==> Patch 3
- 1992-09-17-06:27-ecuicmd.c-wht@n4hgf-add <7-bit kbd> to stat
- 1992-09-17-05:33-mapkey/README-wht@n4hgf-0xE0 should read 0xE1
- 1992-09-17-05:16-ecuxkey.h-wht@n4hgf-finally, 0xE1-0xFA as promised in 3.10
- 1992-09-16-14:13-ecunumrev.c-wht@n4hgf-add M and F version qualifiers
- 1992-09-16-13:54-ecuusage.c-wht@n4hgf-add fkmap usage
- 1992-09-16-13:33-funckeymap.c-wht@n4hgf-add fkmap -l name
- 1992-09-16-13:29-termecu.h-wht@n4hgf-add TERMECU_UNRECOVERABLE
- 1992-09-16-13:29-ecusighdl.c-wht@n4hgf-add TERMECU_UNRECOVERABLE text
- 1992-09-15-18:52-ecutty.c-wht@n4hgf-left some debug code in patch01 dammit
- 7. Information on tty "Device busy" errors and color support
- have been added to README.Q-and-A. Obsolete information was
- removed.
- 8. The -l switch was added to the fkmap commands:
- fkmap -l <name>
- The -l form reads an entire funckeymap definition matching <name>
- from ~/.ecu/funckeymap (if not found there, in a file by the same
- name in the library directory). This form behaves exactly
- in the same manner as the command line switch -F.
- Due to the drastic nature of this command, if it fails to
- execute properly, ECU terminates itself. Note that
- improper use of this form of the command can still render
- ECU an albatross (with Home unrecognizable).
- 9. The original high-bit character space assignments for Alt-A
- through Alt-Z that I chose for ECU made good sense ... to a
- parochial American. Michael Traub <emory!btcs.bt.co.uk!traub>
- sets me straight, but mapkey/README was incorrect. Each hex
- value was off by one.
- 10. If the console has parity enabled, the interactive stat
- command now reports <7-bit kbd>. Knowing this can be important if
- you are using Alt-[A-Z]. Or if you are trying for some kind
- of unlikely tandem 8-bit transparent path (telnet to a box, run
- ecu to call home, login, use ECU there to talk to your amateur
- radio PK-232/MBX TNC over 14 MHz AMTOR to the UK to a Kantronics
- TNC hooked to an SCO box, login, make an ECU call to a certain
- Universal Import-Export ... uh, hi -- I seem to have dozed off).
- 11. At least one ISC SVR3 user had a Devices entry with the
- modem control ",M" suffix I thought was only used in SVR4 UUCP.
- The suffix presence is now detected on all platforms.
- 12. ecusea.c had two fcntl.h inclusions. XENIX could not
- handle this.
- ==> Patch 4
- 13. jeff@samantha.chi.il.us (Jeff Johnson) suggested a change
- in the SVR4 LCK.. logic, stating that the use of <sys/sysmacros.h>
- is deprecated.
- > Here is an excerpt from my <sys/sysmacros.h>:
- >
- > WARNING: The device number macros defined here should not be
- > used by device drivers or user software. Device drivers
- > should use the device functions defined in the DDI/DKI
- > interface (see also ddi.h). Application software should make
- > use of the library routines available in makedev(3). A set of
- > new device macros are provided to operate on the expanded
- > device number format supported in SVR4. Macro versions of the
- > DDI device functions are provided for use by kernel proper
- > routines only. Macro routines bmajor(), major(), minor(),
- > emajor(), eminor(), and makedev() will be removed or their
- > definitions changed at the next major release following SVR4.
- 14. On some systems, the video attributes were not reverted to
- "normal" after some reverse video or underlined strings (e.g,
- "[interactive mode]").
- 15. I removed the Metro Link pts support. This was quite obsolete
- since only very early Metro Link software used pts'.
- 16. FAS 2.10 users are getting SIGUSR1 sent to the transmitter.
- I suspect this is a bug in FAS evoked by the kill(getty,SIGUSR1)
- performed by ecuungetty, but I am have no real clue. This needs
- resolving, but I have little time right now. This patch adds
- signal(SIGUSR1,SIG_IGN) to eliminate the problem.
- 17. Console xon/xoff support has been added. EMACS users
- lament the loss of ^S/^Q. (I personally consider it evolution
- in action :->). A new inetractive and a new procedure
- command have been added Also, the status is reported by
- the interactive stat command.
- conxon on - honor xon/xoff locally
- conxon off - pass ^S/^U to remote
- If you turn conxon off, there will be no local software flow control
- so you probably need hardware flow control for proper operation.
- Refer to the rtscts command descriptions for more information
- (I pray you are using a tty driver that supports the kind
- of hardware flow control your modem requires).
- 18. The procedure file transfer commands did not get
- rearranged to look for the file transfer programs in the
- ecu library directory.
- 19. Chains of else statements may fail to operate properly
- in certain arrangements. The known failure was fixed.
