[USR-TC] Change Login Prompt?

OK, this is probably documented somewhere, but I can't seem to find it in my archives right now. Does anyone know how to change the login prompt on an ARC when dialing in via modem? I can see it when doing a "show connection settings", but can't quite figue out how to change it. I need it to say "Username:" rather than "login:". Running TCS 4.5 ARC code 5.3.110 Thanks in advance! Brad
