Xenix login source

[Robert J Woodhead]

I am running SCO Xenix 386 on Tandy 4000 and 4000lx boxes.  I am setting up
a special access system and want to bypass login; in other words, when 
activity is detected on a serial line, I want to spoof the login procedure,
log into a specific account, and start running my program.

Please tell me if there is an easy way to do this.  Once my user gets to
a shell, it's easy for me to set up his profile so he starts running my
program.  In fact, I can probably have my program as the shell.  The tricky
part (to my unenlightened eyes) is getting him to that point without him
having to see the login: and password: prompts.

If I had the source code to Xenix's login, this would be trivial as I could
just cut out the getting of the login name and password and simply assign
them to my defaults.

So, any suggestions?
