This is an updated version of old_notes/README.SCOTTY
which I am *sure* you already read a long time ago, heh heh :)

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
