I'm trying to add a second dial-up line to a Linux server without much luck. I've followed the serial howto, step-by-step 3 times but can't get it to work. The modem works just fine to dial out, but when you dial in, it doesn't give you a login prompt. I am using "agetty", the modem is on ttyS16, connected using a 16 port BocaBoard, and the modem itself is an AT&T Dataport 28.8. And "yes", I did add a line to my inittab to run agetty on ttyS16. I'm sure I've overlooked something simple but damned if I can figure it out.
