Setting up a UMTS connection using a KPN mobile connect card

Preparing

First you will need to see which serial port is used by your UMTS card.
So plugin your KPN Mobile connect card and start up the PCMCIA service.

# /etc/init.d/pcmcia start

Then you will see something like this in your dmesg output:

ttyS1 at I/O 0x2f8 (irq = 19) is a 16550A

So ttyS1 is our serial port.

Config files

Make sure to change the ttyS# in the config files.
vi /usr/bin/umtsinit

#!/bin/sh
DEFAULTPIN="0000";
TTYDEV="/dev/ttyS1";
if [ $1 ] ; then
PIN=$1;
else
PIN=$DEFAULTPIN;
fi
echo "at" > $TTYDEV;
sleep 1;
echo "at+cpin=\"$PIN\"" > $TTYDEV;
echo "PIN send to $TTYDEV";

vi /etc/ppp/peers/umts
