SERIN Not Working, SEROUT Working

[cc1984]

I pull the diode, thanks. I'll keep on trying, thanks for you help.

I made a reduced size test program and still got the same results. Finally, with nothing else to try I changed the SERIN pin from PORTB.7 to another pin I was not using (PORTC.1). Works like a charm.

I guess it is either a bad chip or some obscure setting for portb.7 I missed. Thanks for all the help.

Interesting. I still do not see the problem in your code (PORTB.7) so it must be hardware...
Or maybe the wrong pin,,, typo???

rcx var PORTB.7 'rs-232 input on portc.7

Or a bad connection?

Could be a bad connection. I have it installed on a test board. I am making the permanent board which should only be traces, not a bunch of wires. Hopefully, that will remove my ghost.

Thanks for all the help, unfortunately the code was the fun part, drawing up the circuit and making the cca is not as fun.
