[comp.lang.c] problems using stdaux

re: problems using stdaux --
1. You don't say what protocol your C compiler uses w.r.t. your COM-port,
   leaving open the possibility that it is defaulting to your non-existent
   COM1 and thereby ignoring your COM2-port.

2. A COM-port must always be initialized to: baud-rate, word-size, number
   of stop-bits and (optionally) parity. I can assure you that if you have
   not properly initialized your designated COM-port, you can expect NO
   communication. (Indeed, there are other factors to consider, such as
   radiation interference to your COM-line from the monitor, but adequate
   shielding should remedy that.)

3. All this begs the question of what your C compiler is really doing
   with your COM-port. Does your documentation mention anything about
   initialization via some C system-call, containing baud-rate, parity,
   number of stop-bits, and word-size?
