29  *      isic - I4B Siemens ISDN Chipset Driver for Asuscom ISDNlink 128K PnP
30  *      =====================================================================
31  *
32  *      This driver works with Asuscom ISDNlink 128K PnP ISA adapter,
33  *      which is based on Siemens IPAC chip (my card probes as ASU1690).
34  *      Older Asuscom ISA cards are based on different chipset
35  *      (containing two chips) - for those cards, one might want
36  *      to try the Dynalink driver.
37  *
38  *      This driver is heavily based on ELSA Quickstep 1000pro PCI
39  *      driver written by Hellmuth Michaelis. Card initialization
40  *      code is modeled after Linux i4l driver written by Karsten
41  *      Keil.
