Metz Open Source
As of today, Metz doesn’t publish open source code on its company website, but you may ask their customer support and they’ll send you a CD-ROM. I received a disc containing source code for Chassis 610/611/612 LCD-TV models.
Speedport ISDN Adapter
These devices are used by customers of Deutsche Telekom as ISDN-to-SIP gateways. Currently there doesn’t seem to be much public information about it, so I’ll make a start.
The ipw2200 device driver limited me to use only 11 channels for wireless LAN, even though I bought my notebook in Germany, where channels 1 to 13 may be used. Although other people on the net faced the same problem, nobody came up with a simple and permanent solution like writing the country code to the card’s EEPROM with just a few commands.
