RS232 into 2 PC ports

I have a serial connection from a MAX232 on my PIC board to an RS232 port on my PC. The data are used in a PC graphics and PIC-control application, using both the TX and RX lines.

Is there any reason why I cannot split the RX line at the PC into 2 so that I can feed a second RS232 port on the computer? The reason for this is that I want to run a completely separate PC data processing application. The TX control line would remain connected to the other PC RS232 port, for control over the PIC.

You can share the RX line on the PC with another. Both will get the same data from your PIC.

Jerson,

Thanks for that advice. My problem is solved!
