That's possible, I suppose.  That's relatively easy to test.  You can
disable sync negotiation by either compiling with flags 0xff00 (I think)
or by setting sc->sc_minsync = 0 around line 297 of esp.c (where it's
set to 1000/sc->sc_freq).

Not a bad idea.  SCSI termination and cable length is always important.  ;-)

That's good to hear!  You're quite welcome.
