tb6560ahq board

reset = 5000 ?
talking about the parport reset time?
but what i tryed to disable are the parport pin output reset, did i the right thing?
my 6560AHQ board always has worked with that value, since i didn't know what it was, i didn't touch that never!
today only tried to change:
Slen: 1
SS: 0
DH: 30000
DS: 30000

to:
Slen: 5000
SS: 5000
DH: 20000
DS: 20000

but since nothing changed in the motion (even if few seconds of movements), i thought that i didn't understand so much of what i studied in the manuals!!

so, what do the reset time essentially is?

good infos. thanks!
these should be somehow added in the documentations.
