 This question might be more appropriate in the TECH or DR_DEBUG echo,
 but because I've had similar problems, using QB/QBX, I'll answer it.

 1st, QBX and Telix seem to have a problem when Telix is loaded first.
 If you have a 16550 UART on that COM port and Telix is loaded first,
 Telix will leave the 16550 FIFOs turned on, which somehow causes a
 lock-up problem for QB/QBX Communications programs.
 I'm still waiting for an answer to the question,
 "How do you turn OFF the 16550 FIFOs?"

 2nd, if you only have 2 com ports, most system reporting programs will
 report them as COM1 and COM2, even if they are something else.
 Check and make sure that the internal modem is setup for COM2, not
 for 3 or 4.
