Dumb question: Is it possible to use Arduino's serial TX as a multicast channel, i.e. have more than one receiver listen to it simultaneously? I'd like to broadcast messages to another Arduino and (via a MAX232) to a PC.

Thanks in advance!

Sure. The electrons don't care how many listeners there are.
