What is the maximum number of output lines you could have that would be
outputting RS232 data streams (not Rx) on a say 16F877 ?
These would be sent to a RS232 line driver.
Each RS232 stream would be required to send a single ASCII code for 1A,
1B, 2A, 2B, etc up to the maximum outputs I guess, repeated every about
5 times a second.
