We have retail store users who want to dial in and send orders to our SCO Openserver 5 computer. They are dialing in with Xmodem protocol to send us a file, we process it and send the results back. We can't change their software, which is not setup to respond to a login, so we need to bypass the login and have a script immediately run to accept this file whenever a call is answered. We could tie this to a particular tty port, and since this system will be used only for this function, we can disable the security altogether if we need to. How can we disable the login for a particular port or for the whole system, but still tie that port to a profile so that a program is started after the phone call is connected?
