That sounds horribly complex. It shouldn't matter what device I
connect to the RS-232 end of the adaptor cable any more than it would
if I were plugging things into an RS-232 port bolted onto the chassis.
For the record though I'm likely to connect other computers, a modem,
a mobile phone (pretending to be a modem), a TNC, microcontrollers, a
GPS receiver, a PBX, an HVAC controller, terminals, printers and other
random pieces of equipment that sport serial ports. These won't all be
connected at the same time though.

That sounds perverse. Happily the adaptor appears as just another tty,
so I should be able to treat it normally without resorting to USB-
specific software. I just wondered why I didn't have a corresponding
outbound dty device and where "cu" was kept.
