NAME

       plipconfig - fine tune PLIP device parameters

SYNOPSIS

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

DESCRIPTION

       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 options.

OPTIONS

       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.

NOTE

       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.
