RocketModem Driver Source Package for Debian / Ubuntu
A couple of months ago I posted about using the current model Comtrol RocketModem IV with Debian / Ubuntu Linux. Ubuntu/Debian includes an older “rocket” module driver in-the-box, which works well for older RocketModem IV cards. But for the newest cards, it does not work at all. The current RocketModem IV is not recognized by the rocket module in-the-box in Linux, it requires an updated driver from Comtrol.
With some work (mostly outsourced to a Linux guru) I now present a source driver package for the 3.08 “beta” driver version:
Comtrol ships the driver source code under a GPL license, so unless I badly misunderstand, it’s totally OK for me to redistribute it here.
To install this, you follow the usual Debian driver-build-install process. The most obvious place to do so is on the hardware where you want to install it, but you can also use another machine the same distro version and Linux kernel version as your production hardware. Some of these commands must be run as root.
dpkg -i comtrol-source_3.08_all.deb
module-assistant build comtrol
This builds a .deb specific to the running kernel kernel. When I ran it, the binary .deb landed here:
/usr/src/comtrol-module-2.6.22-14-server_3.08+2.6.22-14.52_amd64.deb
Copy to production hardware (if you are not already on it), then install:
dpkg -i /usr/src/comtrol-module-2.6.22-14-server_3.08+2.6.22-14.52_amd64.deb
and verify the module loads:
modprobe rocket
and finds the hardware:
ls /dev/ttyR*
To verify those devices really work (that they talk to the modems on your RocketModem card), Minicom is a conveinet tool:
apt-get install minicom
minicom -s
Rebuilding the source .deb
Lastly, if you care to recreate the source .deb, you can do so by downloading the “source” for the source deb: comtrol-source_3.08.tar.gz then following a process roughly like so:
apt-get install module-assistant debhelper fakeroot
m-a prepare
tar xvf comtrol-source_3.08.tar.gz
cd comtrol-source
dpkg-buildpackage –rfakeroot
The comtrol subdirectory therein contains simply the content of Comtrol’s source driver download, and this is likely to work trivially with newer driver versions (3.09, etc.) when they appear.
