  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.
