GSM0710MUXD(8) System Manager's Manual GSM0710MUXD(8)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.

TERM(1) General Commands Manual TERM(1)NAME
term - turn PC into a dumb terminal [IBM]
SYNOPSIS
term [baudrate] [parity] [bits_per_character] [-dial_string] [device]
EXAMPLES
term 2400 # Talk to modem at 2400 baud
term 1200 7 even # 1200 baud, 7 bits/char, even parity
term 8 9600 /dev/tty01
# 9600 baud, 8 bits/char, no parity, use tty01
term -atdt12345 /dev/tty01
# Start with a command to dial out
DESCRIPTION
Term allows MINIX to talk to a terminal or modem over RS232 port 1. The program first sets the baudrate, parity and character length, and
then forks. The parent sits in a loop copying from stdin (usually the console's keyboard), to the terminal or modem (/dev/tty00). The
child sits in a loop copying from the terminal or modem (/dev/tty00) to standard output. Thus when RS232 port 1 is connected to a modem,
every keystroke typed on the keyboard is sent to the modem, and every character arriving from the modem is displayed. Standard input and
output may be redirected, to provide a primitive file transfer program, with no checking. Any argument that starts with a minus ('-') is
sent out to the modem, usually to dial out. Term accepts several commands that are formed by typing the escape character, CTRL-], and a
letter. Type CTRL-]? to see a list of commands. The subshell command is very important, it allows you to type in a ZMODEM command to
transfer data. Do not quit term to do this, or your modem line will be reset! Term keeps the modem line open on file descriptor 9 while
running the subshell, so you can type
<&9 >&9
at the end of your ZMODEM command to connect it to the modem.
Important note: to use term, it is essential that /etc/ttytab is configured so that there is no shell hanging on /dev/tty01. If there is,
both the shell and term will try to read from /dev/tty01, and nothing will work.
