So, when you say "didn¡¯t bother with others¡± ?does that mean you did not test them or that they are not actually making any connection? ?Using a Crestron 9-pin COM port you must ensure the pins you are not using are not connected. ?In other words you must only have pins 2, 3, and 5. ?If other pins are connected, as in using a manufactured cable with all 9 conductors, there can be problems caused because pins 1, 4, 6 and 9 of the Crestron COM port do not conform to a standard 232 port. ?If nothing else, just use a small needle-nosed pliers and break the unused pins off the male end of the cable (or you can do like my favorite installer and cut the cable and splice together only 2, 3 and 5).

Thanks for the reply. ?I am using AV2. ?I am using one of the com port in my C2COM-3 card, and C2COM serial driver. ?I assumed 2 & 3 are tx and rx. ?The cable I am using is a crossover. ?I verified only 2 & 3 and ground 5. ?Didn't bother with others. ? I monitor the C2COM serial driver's rx$ and tx$ via Toolbox. ?I did see every command that I sent out via tx$. ?But rx$ is always show as . ?I tried to use serial gather to hold on strings in case it just pass through. ?Didn't do anything.
Thanks,
