* 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.
*
* $FreeBSD$
