I have used a pl2303 adapter recently, and was using it to talk to a USR
modem which worked perfectly.  No idea why it wouldn't work with a cisco
unless the cisco was broken.  Of course it could be the usb adapter is
defective, or maybe the cable you are using is defective.

Certainly the line '> ttyUSB0<*1>: ATQ0 V1 E1 -- Backup-Switch>' looks
like at 9600 (as expected) the cisco did send readable text.
