Good point.  I should have mentioned that before as well.  Performing the 
above produces similar results as the code.  Regretably, I see nothing 
returned on cua01 on a call up despite a successful connection.

I've also tried wiring a full RS232 loopback by jumpering RTS/CTS and 
DCD/DSR/DTR as well.  Same result.
