NAME

       gsm0710muxd - a GSM 07.10 muxer

SYNOPSIS

       gsm0710muxd [options]

DESCRIPTION

       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.

COMMAND-LINE OPTIONS

       -d   Fork, get a daemon (default: no)

       -v   Verboser logging (give twice for even more verbose)

       -s <serial port name>
            Serial port device to connect to (default: /dev/modem)

       -t <timeout>
            reset modem after this number of seconds of silence (default: 0)

       -P <pin-code>
            PIN code to unlock SIM (default: <not set>). This is normally  not  needed  but  some
            modems need the pin before enabling the muxer mode.

       -p <number>
            use ping and reset modem after this number of unanswered pings (default: 0)

       -l <filename>
            set logfile name (default: <not set>)

       -x <dir>
            power management base dir (default: <not set>)

       -a <mode>
            additional_functionality  (default:  0).  This  is  a  bit-set  enabling  quirks  for
            different modem. The quirks are: WAKEUP_WITH_SYSFS =  1,  WAKEUP_WITH_SEQUENCE  =  2,
            SIEMENS_C35 = 4, ENFORA = 8, SHORT_INIT = 16.

       -b <baudrate>
            muxer-mode baudrate (default: 115200)

       -B <baudrate>
            serial port baudrate (default: 115200)

       -m <mode>
            Mode (basic, advanced) (default: advanced)

       -f <framsize>
            Frame size (default: 64)

       -h   Show a help message and display current settings.

HISTORY

       The  name  'gsm0710muxd' was chosen because the GSM specs describe this method in document
       7.10.

BUGS/LIMITATIONS

       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.
