Hi all,
Is there any difference between a null modem cable or a modem cable ?
i assume that a null modem cable is a normal cable that i used from cpu serial ports to a modem for dialup.

gsm0710muxd
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.
