 		 #103920 - a dangerous approach
Responding to: ???'s previous message
RS232 in the following way .... then it can transmit 1 character when there is no activity on the RX,
a dangerous approach. This would require The 232 trqnsmitters to be short circuit proof and you would still have collisions.
You do not know of "activity on the RX" till a character is complete (1ms at 9600). Even connecting Rxd to EI0 will fail occasionally albeit much more rarely.
