He did. After asking me to run some tests, Randy said i could send it back. I just got it back yesterday and it's working again. Greg Nowak pegged the problem too -- bad serial cable. I kind of suspected that too but the one thing that made me doubt it was that I couldn't get it to work by jiggling the cable. I think the pins inside the molded end were bad and that may be why jiggling it didn't help. .
