Modem

XO with USB Cellular Modem Adviser: Michail Bletsas, Development: Ankur see more templates or propose new

Steps

The following steps are tested with Franklin CDU-680DOrA Mobile Broadband USB Modem.

1. Insert the modem into an USB slot on XO. The device will be shown as a removable storage on XO. 2. Make a directory and copy the following files in it:

• Packages

1. Wvdial : wvdial-1.54.0-5.2.2.1.i386.rpm 2. PPP: ppp-2.4.4-2.i386.rpm 3. Libwvstreams: libwvstreams-4.2.2-3.fc7.i386.rpm

2 and 3 are the dependencies for installing 1.

• Files

The following files are located under the Linux directory 1. connect 2. itfchg 3. cdu680config : This file needs to be edited for entering your User name and password. 4. execute.sh These are needed for installing the drivers for this particular modem.

3. Run the following script so that the device is recognized as a modem.

Help:Save this script in a new file, give execute permission to it and then run it using bash.

#!/bin/bash
#Installs the required packages: wvdial, ppp and libwvstreams if not installed.
for i in `ls *.rpm`;do rpm -i $i;done &> /dev/null
#End all the services running related to modem
killall wvdial &>/dev/null
killall connect &>/dev/null
sleep 5 
#install drivers and quit "connect"
while read line;do echo $line;echo $line|grep init && break &> /dev/null;done< <(./connect 2>&1) 
killall connect &> /dev/null
ifconfig msh0 down
killall wvdial &> /dev/null
sleep 5
while read line
do  
           echo $line
           echo $line|awk '/DNS/ {print "nameserver "$5}' >> /etc/resolv.conf
done< <(wvdial --config cdu680config 2>&1)

Work in progress here

Possible Work is to develop a generic way of interfacing any modem with XO.
