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.
