plipconfig - fine tune PLIP device parameters


   plipconfig interface [nibble NN] [trigger NN]
   plipconfig [-V] [--version] [-h] [--help]


   Plipconfig  is used to (hopefully) improve PLIP performance by changing
   the default timing parameters used by the PLIP  protocol.  Results  are
   dependent  on  the  parallel port hardware, cable, and the CPU speed of
   each machine on each end of the PLIP link.

   If the single interface argument  is  given,  plipconfig  displays  the
   status  of the given interface only.  Otherwise, it will try to set the


   nibble NN
          Sets the nibble wait value in microseconds. Default is 3000.

   trigger NN
          Sets the trigger wait value in microseconds. Default is 500.

   PLIP speed can in some  cases  be  improved  by  lowering  the  default
   values.   Values  which  are  too low may cause excess use of CPU, poor
   interrupt response time resulting in serial ports dropping  characters,
   or  in  dropping of PLIP packets. Changing the plip MTU can also affect
   PLIP speed.


   If you get no response it is far more likely the irq is wrong and needs
   setting  with ifconfig. The few cases where the default parameters will
   be too fast are those using very  long  cables.  Something  you  should
   never  do as the parallel port is not specified or designed for driving
   long cable runs.
