Well, as I said, wvdialconf makes the lights turn off and on when querying 
/dev/ttyS0, and that's what both minicom and HyperTerminal (com1) are 
pointed to.

I have tried both modems in both ports - same behaviour exhibited. Which 
leads me to believe that it's one of three possibilities: A, both modems are 
broken. B, both cables are broken (the 56k one that plugs into the modem is 
round and small to a 9pin, and was the one the previous owner used I think) 
or C, Both serial ports are broken. The trouble is isolating which of this 
these it is. I'm basically stuck with the equipment that I have, so any help 
is greatly appreciated.

I'm also curious as to what would be involved making the proprietry Linux 
drivers for my winmodem work under Ubuntu 6.10. Why are they so specific?
