[CLUE-Tech] mgetty and ppp troubles on linux dialin server

[daniel]

Hello all,

I am trying to set up a dialin server so I can access my network from abroad.
I have a ZOOM 14.4 external modem connected to ttyS0.  I'm planning to use PAP
to authenticate. The log messages that I see in the server's
/var/log/mgetty.log.ttyS0 log file are:
---

Does anyone have any suggestions on how I might be able to get this working?
One thing that I am unsure about is reading what init string is being used,
and whether that init string is the one suggested from my modem's manual.  The
manual says to use "  AT &F &C1 &D2  ". If the incorrect init string is being
used, I think I need to change that in /etc/mgetty+sendfax/mgetty.config, but
I am not sure how to make that entry.
Any ideas or suggestions are greatly appreciated :)

Thanks,
Daniel
