I don't hack with active components; relays are right out at the limit of my competence. (Okay, I did once optimize some gate sequences in a semi-custom VLSI chip to shave a nanosecond or something off the worst-case throughput time, but that was my *mathematician* hat; I don't have a hardware designer hat.) > David Dyer-Bennet also wrote: > >I think I've got a valid cable.

( Something I don't know anything about!) Good Luck. I've had enough different cable designs fail to tickle enough different software that I have to verify that the port works (swap the modem from the other port). And after that I'm going to have to write my own program to monitor the signal line state and report changes; everything I've tried is comlex enough that I can't be sure I'm using it right.
