  33  * These cards have various combinations of serial and parallel ports. All
  34  * varieties have up to 6 1-bit registers for extended capabilities, named
  35  * "Usr0, ..., Usr5". The functional registers are mapped to the proper
  36  * "Usr" register at attachment time. The only functional registers the
  37  * kernel currently deals with are the registers to enable or disable the
  38  * alternate clock, which permits speeds of the serial port all the way to
  39  * 960Kbps. (In the documentation, those registers are called "Clks0" and
  40  * "Clks1" on the "10x" series, and * "K0" and "K1" on the 20x series.)
