Re: Problems setting up USRobotics SportserFlash Modem

Then, Dr. Vigna, I don't know. I'm working on a Linux setup myself
with a USR Sportster 33.6 modem, and have had some other
difficulties. I'll be bringing home a 56 K modem soon and trying that
to see if the problem is in fact USR and not the software.

Someone posted this recently for their USR sportster modem: I include
it in case it helps.

   Subject: USR intermittently accepts dial-in?

   I am successfully running Hylafax on Linux 2.0.30. I can Xmit faxes. I
   have mfaxgetty and getty configured to accept dial-ups. When I get an
   incoming call my modem answers and I get the login prompt. However, if I
   drop the connection and try a subsequent dial-in the modem does not
   answer and the line sounds dead. (not dial-tone, no ringing tone). After
   a subsequent transmittal the modem will again accept connections. I
   presume that something is not resetting the modem correctly. 

   Could someone suggest what I could so to get some repeatable dial-in
   success?


   I have a USR 28.8 Sportster. The config file looks like this:

   Gettydefs looks like:

   and the line in /etc/inittab

   Set serial, sets the UART to spd_vhi

   This looks like a successful log session:
