A patch for the PLIP driver contained in the 2.4.3 version of the Linux kernel. This patch allows one to use PLIP with computers which have an interrupt-less parallel port and a slow processor. The stock PLIP driver constantly times out on my 80486-based laptop. This patch adds the ability to specify two key values, trigger_wait and nibble_wait, when loading the PLIP driver.
Using this patch and adding the following entry to the modules.conf file on the computers on either side of my PLIP link makes the connection work nicely:
## Because my laptop is so slow. options plip trigger_wait=50000 nibble_wait=300000
