On SCO, TTY devices must be named in the style of:

     /dev/ttyNA
             ^^
             ||
             |`------ uppercase letter for modem control
             |        lowercase for non-modem control
             `--------digit (1-4 usually, but any digit)


tty opened  lock file created
--------   ------------------
tty23       LCK..tty23               violates NA
tty0A00     LCK..tty0A00             violates NA
tty0a00     LCK..tty0a00             violates NA

tty1a       LCK..tty1a
tty1A       LCK..tty1A

tty2q       LCK..tty2q
tty2Q       LCK..tty2q

tty9a       LCK..tty9a
tty9A       LCK..tty9A

tty231a     LCK..tty231a
tty231A     LCK..tty231a

tty%%1a     LCK..tty%%1a
tty%%1A     LCK..tty%%1a

This is the procedure used for any SCO ECU version.

If you are using FAS or other third-party driver, you may use ecu
with ports not normally named in the /dev/tty#N style in one of two
ways under UNIX and one way under XENIX:

     1.  Under XENIX or UNIX, create a link to the port
         with a compatible name:

               ln /dev/ttyF00 /dev/tty1a
               ln /dev/ttyFM00 /dev/tty1A

     2.  Under UNIX, add additional lines to the
         /etc/conf/node.d file and rebuild the kernel
         environment (this is the recommended approach
         for UNIX, as documented in FAS 2.08 and 2.09):

     fas ttyF00  c   48
     fas tty1a   c   48
     fas ttyF01  c   49
     fas tty1b   c   49
     fas ttyFM00 c   208
     fas tty1A   c   208
     fas ttyFM01 c   209
     fas tty1B   c   209
