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.

BUGS

       Non.
