NAME
plipconfig - fine tune PLIP device parameters
SYNOPSIS
plipconfig interface
plipconfig interface [nibble NN] [trigger NN] [unit NN]
DESCRIPTION
Plipconfig
is used to (hopefuly) 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.
- unit NN
-
Sets the number of units of delay. Default is 1.
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.
