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. Here [1] you will find the necessary components that include:
- 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 that your SP provides. After entering your username and password. 4. execute.sh These are needed for installing the drivers for this particular modem.
3. Run the run.sh script so that the device is recognized as a modem.
