500KB? that would be great... I've only maxed at about 220KBytes/sec. To
get the fastest throughput, you must have to use mode 4, right?
lepton:~# insmod paride
paride: version 1.02 installed
lepton:~# insmod epat
paride: epat registered as protocol 0
lepton:~# insmod pd drive0=0x378,0,0,4,0,1,0,0
pd: pd verson 1.03s, major 45, cluster 64, nice 0
pda: Adapter not found
pd: no valid drive found
Initialization of pd failed
If I don't specify the mode, the pd driver loads, using mode 2. Setting the
delay to zero doubled my throughput, but if I can double it again, that would
be great. My machine is a fairly old laptop, so am I stuck at mode 2? How
can I find out?

trying to optimize transfer rates to a Syquest EzFlyer 230
BTW: if the advertized transfer rate of the parallel port EzFlyer is
1.2MB/sec, why is 500KB the maximum achieved throughput under linux? Not that
I'm complaining. The paride/parport project has done Great Things for the
