RS232 feeding 2 PC ports

Post by manxman » Mon Aug 25, 2008 11:10 am

:?

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.
