assuming the following:
1.) i would like to send data to an arduino board (one hw serial port) from two devices - one of them is the built in usb->serial converter, while the other is an RFID reader
2.) the devices don't talk very often, and they never do it at the same time
3.) i cannot use the software serial library, due to the limitations
from the above, is it possible to drive one serial input with two outputs? (or is this just a bad idea and i should look at getting a board with more ports?)
thanks in advance,
