I think RS-232 does not support multinode configurations (I think). You may need to use more than one external transceiver and selecting them by some kind of enable signals...
Is just a suggestion.

Good Luck,

Juanma

You can use a software UART for one and a hardware UART for the other.

Read the #use rs232 directive in the manual - it explains how to do it.
