PLIPCONFIG(8)                            Linux System Administrator's Manual                            PLIPCONFIG(8)



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.  Other‐
       wise, 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.
