serin trouble with PIC16F877A

[thasatelliteguy]

OK, I put a pause 500 in front of the serin command with no change. Two questons... 1.Why did you think that would work? (Not being smart here, I assume you had logical reasoning or experience that might be of some use someday) 2. Can I use multiple qualifiers? Like if I want to reject everything except 1 2 3 or 4?? thanks!

You have made my day

You have a loop that is constantly being executed except for the 500 pause. You Tx then instantly Rx with no time for a response to be sent.

Well that was my thinking but obviously there is more to it than I first thought.

try

Serin RX, 2, 500,MainMenu,cereal

serin will wait 500 msecs waiting for data to come in. cereal you have as a word it only needs to be a byte.
