Possible, yes, but you do NOT want to do it THAT way. It bypasses all system access controls. set up a special purpose userid with a login script that runs a terminal program (via 'exec') like kermit with a start-up script for that program that selects the proper port and then sets the needed serial settings, and goes into 'connect' mode. whed they exit the terminal session, they're automatically logged off the system.
