/* gerdes_amd7930.c,v 0.99 2001/10/02
*
* gerdes_amd7930.c Amd 79C30A and 79C32A specific routines
* (based on HiSax driver by Karsten Keil)
*
* Author Christoph Ersfeld <info@formula-n.de>
* Formula-n Europe AG (www.formula-n.com)
* previously Gerdes AG
*
*
* This file is (c) under GNU PUBLIC LICENSE
*
*
* Notes:
* Version 0.99 is the first release of this driver and there are
* certainly a few bugs.
*
* Please don't report any malfunction to me without sending
* (compressed) debug-logs.
* It would be nearly impossible to retrace it.
*
* Log D-channel-processing as follows:
*
* 1. Load hisax with card-specific parameters, this example ist for
* Formula-n enter:now ISDN PCI and compatible
* (f.e. Gerdes Power ISDN PCI)
*
* modprobe hisax type=41 protocol=2 id=gerdes
*
* if you chose an other value for id, you need to modify the
* code below, too.
*
* 2. set debug-level
*
* hisaxctrl gerdes 1 0x3ff
* hisaxctrl gerdes 11 0x4f
* cat /dev/isdnctrl >> ~/log &
*
* Please take also a look into /var/log/messages if there is
* anything importand concerning HISAX.
*
*
* Credits:
* Programming the driver for Formula-n enter:now ISDN PCI and
* neccessary this driver for the used Amd 7930 D-channel-controller
* was spnsored by Formula-n Europe AG.
* Thanks to Karsten Keil and Petr Novak, who gave me support in
* Hisax-specific questions.
* I want so say special thanks to Carl-Friedrich Braun, who had to
* answer a lot of questions about generally ISDN and about handling
* of the Amd-Chip.

*
* This file is (c) under GNU PUBLIC LICENSE
*
* Notes:
* This driver interfaces to netjet.c which performs B-channel
* processing.
*
* Version 0.99 is the first release of this driver and there are
* certainly a few bugs.
* It isn't testet on linux 2.4 yet, so consider this code to be
* beta.
*
* Please don't report me any malfunction without sending
* (compressed) debug-logs.
* It would be nearly impossible to retrace it.
*
* Log D-channel-processing as follows:
*
* 1. Load hisax with card-specific parameters, this example ist for
* Formula-n enter:now ISDN PCI and compatible
* (f.e. Gerdes Power ISDN PCI)
*
* modprobe hisax type=41 protocol=2 id=gerdes
*
* if you chose an other value for id, you need to modify the
* code below, too.
*
* 2. set debug-level
*
* hisaxctrl gerdes 1 0x3ff
* hisaxctrl gerdes 11 0x4f
* cat /dev/isdnctrl >> ~/log &
*
* Please take also a look into /var/log/messages if there is
* anything importand concerning HISAX.
*
*
* Credits:
* Programming the driver for Formula-n enter:now ISDN PCI and
* neccessary the driver for the used Amd 7930 D-channel-controller
* was spnsored by Formula-n Europe AG.
* Thanks to Karsten Keil and Petr Novak, who gave me support in
* Hisax-specific questions.
* I want so say special thanks to Carl-Friedrich Braun, who had to
* answer a lot of questions about generally ISDN and about handling
* of the Amd-Chip.
