Subject: Re: [PARPORT] ppscsi/epst mode question(slow scanning w/ hp5200C
Ahh... Sounds like the rant that I did some 30 months ago when the
original EPP enhanced ZIP driver failed for my machine (which is due
for retirement in several weeks). I ended up maintaining the driver,
if you are not careful you might end up maintaining the epst driver
(we could use a few more maintainers).

Please send me a copy, I have been meaning to make chipset specific
extensions to parport but have had "project commitments". (one point
the comment of "if we make sure he doesn't leave the building there
can be no way he could be run over by a bus" was made...)

I admit it was a long shot, the code is really for 87xxx series IO
chipsets. I have never encountered the 89xxx series but I might soon
have a test machine when I finally get my order through.

The way I found out about the dmesg command was looking through the
/bin directory on a HP-UX machine trying to figure out what all those
utilities are for. Suprisingly I found it also present under Linux.

Keep working on the chipset kludge routine.
Tim, is there anywhere in parport_pc we can "bury" these chipset
