* isic - I4B Siemens ISDN Chipset Driver for Asuscom ISDNlink 128K PnP
|
|
* =====================================================================
|
|
*
|
|
* This driver works with Asuscom ISDNlink 128K PnP ISA adapter,
|
|
* which is based on Siemens IPAC chip (my card probes as ASU1690).
|
|
* Older Asuscom ISA cards are based on different chipset
|
|
* (containing two chips) - for those cards, one might want
|
|
* to try the Dynalink driver.
|
|
*
|
|
* This driver is heavily based on ELSA Quickstep 1000pro PCI
|
|
* driver written by Hellmuth Michaelis. Card initialization
|
|
* code is modeled after Linux i4l driver written by Karsten
|
|
* Keil.
