C-kermit (available from comp.unix.sources archives, if not elsewhere)
will handle chat-scripts in the general syntax of L.sys files.
Strange as it may seem, this may be exactly what you need for strange
`networks' where you need versatility, if not sophistication.  If you
don't want to use kermit, you can always quit once the connection
has been estabilshed and then start your target program.

Since you asked for some examples, I'm including a shell script that
I use to a nearby VAX/VMS cluster twice a day for new mail.  This is a real
hack, but it's a somewhat creative use of kermit, and for the moment
it's the only means we have.  It could be made much more elegant, but
this is the easy fix.  I hope you find it useful.

#!/bin/sh	This is vmsmail
# script to poll the VMS system for any new mail using C-kermit
# Each user to poll is specified on the command line, which would
# typically be in a crontab file.  Every (UNIX) user has a the vax 
# login sequence in the file .vaxrc in # his/her HOME directory.
# All new mail is kept in a temporary file on the vax called NCL.MAI.
# If there is no new mail, this file doesn't exit and the kermit 
# `get' falls through and the script logs off.

if [ -r /usr/spool/uucp/LCK..tty0 ]
then echo "VAX poll failed...line tty0 locked" | mail root
     exit 0
fi
