Notes: Multitech MultiModem GPRS and SLES10 SP1

Keywords: SuSE Linux Enterprise Server 10, udev, modem, GPRS, SMS


The Multitech MultiModem is a USB GPRS modem that is capable of sending and receiving SMS text messages. It uses a Texas Instruments USB to serial convertor and while the default Linux kernel does have an appropriate driver module for this (namely ti_usb_3410_5052) - it is incapable of loading the necessary modem firmware. Fortunately, a suitable kernel module has been written and is available at - however, due to changes in later kernels, the module wouldn't compile on SLES10 SP1.

I took the supplied patch for the 2.6.13 kernel, applied it to 2.6.13 and then looked at the differences between 2.6.13 and 2.6.16 (as shipped with SLES10 SP1). I then modified it so that these differences were incorporated while keeping the newer, required features. This was a quick, iterative process largely performed without consideration of the kernel internals.
