SERIN Not Working, SEROUT Working

[mackrackit]

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?
