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

NAME         top

       plipconfig - fine tune PLIP device parameters

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       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         top

       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.
