you shure aboute the PSPS? if not forw. to the list pls
well i first did some test with the "hardware enhanced" mode 010
and did PIO into the fifo with a switch statement and HighWater and
LowWater marks this gave me about 5-600kB transfer rate
but i have more need of fast input than output and I dislike keeping the
cpu busy with what is essentially dumb work.
Next step was to implement DMA and last Step was
ECP and reverse transfers.
well everything works, but no reverse transferneither Pio nor DMA; bah
I have tested this on 3 different Platforms under Linux:
my old P133/asusP5n from 95 and a new laptov "Vobis LeBook" PMMX233?
and a brandnew Desktop machine with PII???
ecp Hardware is 8bit wide ( cfgA/B ). al show the same behaviour.
Did you get any rev transfers in mode 011/ecp acomplished?
