|
|
.SH NAME
|
|
gsm0710muxd \- a gsm 07.10 muxer
|
|
.SH SYNOPSIS
|
|
.B gsm0710muxd [options]
|
|
|
|
.SH DESCRIPTION
|
|
.B
|
|
A gsm muxer is needed to keep a ppp/gprs up & running while sms and
|
|
calls are still signaled on another channel. Some modems even support
|
|
using gprs while a call is active, others suspend gprs during calls.
|
|
|
|
The muxer supports various options to change the behaviour for
|
|
different modems. Use -h to see a brief help screen.
|
|
|
|
All logging is done through syslog, see the syslog for errors and
|
|
warnings.

|
.SH BUGS/LIMITATIONS
|
|
|
|
.B gsm0710muxd
|
|
There may accure bufferoverruns and thus missing data between muxer
|
|
and client under certain situations.
|
|
|
|
Some settings could be determined by a AT-command at startup. This wouldn't be
|
|
much reliable because modems often lie so i did not invest to much work in
|
|
this.
