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 managment 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 choosen 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.

Name
mdc - DS5100 serial line driver

Syntax
device mdc0 at ibus? vector mdcintr
device mdc1 at ibus? vector mdcintr
device mdc2 at ibus? vector mdcintr

Description
A DS5100 base system (mdc0) provides four asynchronous ports. An optional asynchronous card (mdc1 and mdc2 ) can be added to supply eight
additional ports.

The mdc ports are used as follows:

Port Usage Connector

0 Console port 6-pin MMJ on CPU board
1 Local terminal 6-pin MMJ on CPU board
2 Full modem control port 25-pin D-Sub on CPU board
3 Local terminal 6-pin MMJ on CPU board

An optional asynchronous board provides an additional eight lines:

4 Local terminal 6-pin MMJ
5 Local terminal 6-pin MMJ
6 Full modem control port 25-pin D-Sub
7 Local terminal 6-pin MMJ
8 Local terminal 6-pin MMJ
9 Local terminal 6-pin MMJ
10 Local terminal 6-pin MMJ
11 Local terminal 6-pin MMJ

The console baud rate is set to 9600 baud by default. You can change this by setting the baud environment variable from console prompt.
Each communication port from the serial line controller behaves as described in the reference page and can be set to run at any of 16
speeds. For the encoding, see

You can establish the state of port 2 (port 6) by specifying either modem or nomodem as part of the file entry.

Restrictions
The speed default is to 9600 baud on the console port. The console device must be set for 8-bit character length with one stop bit and no
parity. The driver enforces these restrictions; that is, changing speeds with the command may not always work on console ports.

Files
Console terminal

Full modem control or local terminal
