BMost likely the problem is the cable.  Many standard cables have the following
setup (assuming you are using a GS type DIN-8):

DTR: Pin 1 ---> Pin 20: DTR and Pin 4: RTS
CTS: Pin 2 <--- Pin 6:  DSR
TD-: Pin 3 ---> Pin 2:  TD
GND: Pin 4 ---- Pin 7:  SG
RD-: Pin 5 <--- Pin 3:  RD
TD+: Pin 6 NC
GPi: Pin 7 NC
RD+: Pin 8 ---- Pin 7 (or pin 4 on the Minidin)

This gives you output handshaking (the computer can stop the modem, but not
vice-versa).  The problem is Pin 2-- it should be connected to CTS (Pin 5)
not Pin 6 (which on the USR seems to be the same as Carrier Detect)

(If you are using a DB25 like the Apple Super Serial card, disregard this
sentence)
