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,

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. _________________ Regards, Andrew
