Red Hat Bugzilla – Bug 66426
vgetty fails on USR Sportster
Last modified: 2007-04-18 12:43:04 EDT
Description of Problem:
The vgetty does not work with US Robotics Sportster modems. It answers the
incoming call, but then it immediately hangs up the line. After thet it
continues the normal operation (starting the call_program or playing the welcome
message). The line is already hung up at that time, however.
Version-Release number of selected component (if applicable):
1.1.28 (maybe earlier as well).
100% (tried 10 USR modems some of it with different firmware). It worked on
RedHat 5.2 systems (dont know the version of mgetty-voice package in RH5.2).
Steps to Reproduce:
1. configure vgetty on a serial line
2. connect the USR sportster to the line
3. call the phone number
It picks up the call, but immediately hangs up.
Playing the welcome message, then recording the data.
I've discovered (by re-typing the AT commands from vgetty log file by hand) that
it hangs up the line after the AT#VLS=0 command. I've found this command in the
mgetty-1.1.28/voice/libvoice/US_Robotics.c file near the line 292. After
changing this to "AT#VLS=0A" it started to work. Patch is as follows:
--- mgetty-1.1.28/voice/libvoice/US_Robotics.c.orig Mon Jun 10 13:41:05 2002+++ mgetty-1.1.28/voice/libvoice/US_Robotics.c Mon Jun 10 13:34:10 2002

Apologies for the long delay in processing this bug - it got lost somehow.
As I have no USR Sportster modem which which to test, I cannot verify this
patch. I have sent the patch upstream and will incorporate it when it appears
in the next upstream release.
