GSM Card Configuration
This works for firmware 2.1.3 and up. The GSM card can be used either as Dial-in or
Dial-out profile, but both will be connected through GSM modulation. You also have the
option to close a ppp connection using GSM (CLI mode). All these options will be
shown in the steps below:
VI Method
Step 1 - In /etc/mgetty/mgetty.config, add this entry:
port ttyS2
data-only y
init-chat "" \d\d\d+++\d\d\dATZ OK
Where ttyS2 may have to be changed to the serial port that will be assigned to the
GSM card, eg. replace ttyS2 by ttyS9 for an ACS8.
Step 2 - If the SIM card needs a PIN, edit /etc/pcmcia/serial.opts. Uncomment
the line
INITCHAT="- \d\d\d+++\d\d\datz OK at+cpin=1111 OK"
and replace '1111' by the PIN.
Step 3 - Add '/etc/mgetty/mgetty.config' to /etc/config_files and call saveconf:
# echo /etc/mgetty/mgetty.config >> /etc/config_files
# saveconf
Insert the card. The card should flash red first. After the PIN is sent, the LED stays red,
until the card found network. It then flashes green.
CLI Method
To configure a GSM PCMCIA card using the CLI, follow the steps:
Step 1 - Open the CLI interface by issuing the command:
# CLI
Step 2 - Configuring the GSM parameters.
Depending the way you wish to use the GSM card, some parameters do not need
to be configured. Here we will explain all configurable parameters:
PIN NUMBER: The command below will configure 1010 as PIN number:
cli>config network pcmcia 2 gsm pin 1010
