I don't know if anyone has tried this or know how it would work but I am trying to get my Pronto RFX9600 to send serial commands to a com port on my PC and for the PC to relay those commands to an audio device via another com port. I've tried using a null modem cable as well as a serial cable with a gender changer but the PC does not seem to be receiving any commands from the RFX9600. I have tested the cables, the serial port on the RFX9600 as well as my PC com ports. They all work independently but for some reason when I send commands that should be coming out of the RFX9600 port, the PC does not pick it up.

What are you trying to do?

Do you wand the rfx9600 to comunicate with a PC and an audio device at the same time?

RFX9600 communicates normally with a PC.

Use Br@y's terminal to see that the communication works. Maybe you have not configured the PC com port to work with the RFX. I meand the handshaking and stuff.

I want the RFX to send commands to the PC which will then read it on one com port and relay it to another com port. The reason I am doing this is because I am writing a program that will also control this piece of equipment and it only has one com port. Since you can't send commands to the RFX, this is the only method I can think of to allow the RFX and my PC to control this device.

Why not communicate to the PC via IP?

You can with a bit of know how use one seial port to send to 2 others, only one device will be 2 way and the other one way..

Or

Use 2 seial device to control one device with a serial port..

you just need to use signal Diodes IN1418 in the right TX or RX connection ..

take a look at RS232 sniffer on Google and im sure your work it out :)

BluPhenix, thanks for the suggestion on br@y's. I was able to confirm that the ports are working ok. I guess I must have screwed something up with my VB program since one com ports reads and writes fine but the com port connected to my audio equipment with a null cable doesn't read and write correctly although it shows up when using Br@y's. I should have enough to do on right now.
