On SCO Xenix V/286 or V/386:

Without doing much hacking, this may be a quick or temporary fix. Let say
the serial line is 'tty1a' and the acouunt you want to login in is 'acc'.

1. Disable the getty on the line

disable tty1a

2. Edit /etc/gettydefs to create a new entry with AUTO keyword in the six
   field. e.g.

X # B9600 ... # B9600 ... # \r\nlogin: # X # AUTO

3. Edit /etc/ttys so that you have an entry

1Xtty1a

4. Create an account named 'tty1a' so that in /etc/passwd you have an
   entry

tty1a:PASSWD:UID:GID:DESCRIPTION:PATH:YOUR-FAVOURITE-SHELL

5. Enable the line

enable tty1a

6. If you just want to run a program (executable, not shell script), you
   can simply replace your favourite shell to the program you want to run.
   OR change the keyword AUTO to the name of your program (That may be the
   best solution you want).

There may be minor variations to the above setup, but I know it is feasible
and does not require any hacks to existing Xenix utilities. Please refer
to gettydef(F) for more details.
