Heinz,
Look at the zip drive driver code ppa.c in the kernel source. I thought
it was useful in explaining how to do 16 and 32 bit transfers.
cpeacock has a 8 page document on EPP operation but it's sketchy on the
details of 16 and 32 bit transfers. Do a search for senet, cpeacock,
epp and you should find it. It's a pdf.
I've done 1M/s x single byte reads through an ISA parallel port for a
home-brew video digitiser. There wasn't much time for anything else so
it would be difficult to sustain those transfer rates. Using EPP 32 bit
transfers would make a big difference.
cheers,
Stuart W
