       gsm0710muxd - a GSM 07.10 muxer


       gsm0710muxd [options]


       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.


       -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.


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


       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.
