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
Sets the nibble wait value in microseconds. Default is 3000.
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.
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.
