Serial port communications is nearly always a headache... I used it for many years! Did you check the cable? Does the cable implement the DTR/DSR and/or CTS/RTS lines (in both directions?) Some cables have strange (and incorrect) connections at each side. Some software also uses those lines differently from others. One of the pairs (DSR/DTR I believe) is software controlled, so they can be activated at different times. To avoid cable problems you can try to enable XON/XOFF, and disable hardware handshaking. This is simpler to debug, and even the simplest cable should work (3 wires only).
