Dial-up modems

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.

Your agetty may be re-spawning too fast, if it does you may see a message on the screen and you are sure to see something on /var/log/messages.  Have you set your modem with E0 and Q1?  This is sometime the problem as agetty thinks that there is someone on line but it's just the echo from the modem or the result codes.

Have you compiled your own agetty or are you using a precompiled one.  I reccomend to compile your own.

This is an example of my inittab syntax just in case it would be something simple like a typo:

d3:3:respawn:/sbin/agetty -h -t60 38400 ttyR3  

I am using a rocketport.

You say you don't get a login prompt, do you get garbage on the screen or absolutely nothing?  Does your modem even auto answer?

If this does not solve your problem, send me more info such as OS version, agetty version.
