This reminds me of the time 8 years ago when I tried to transfer the entire contents of my 540meg Amiga HD to my PC via a null modem cable... I remember that if I set the rate above 38400 the connection would fail... I left it running for over a day before the connection failed... And when I checked, most of the files had errors... I learned a lot from that exercise.
Mostly, that to transfer data, attaching the drive to the PC was best :-)
