Just thought you might like to see the final result. I just hope that others searching or working on serial communications can make use of all that has gone on in this thread

LCD garbage
Maybe I spoke too soon - seems that something corrupts the LCD after a set number of transfers.
Basically the PC applications sends a "Q" every 10 seconds which causes the PIC to respond by sending the stream of digits described above. On the 27th Q the LCD starts to display random characters, initially along the bottom line of the 4 line LCD.
Thinking it might be the application I used the serial port coms app from MCS and manually sent Q's to the PC. on the 27th the same thing happened....
Any ideas on where to start de-bugging ?

Hi Malcolm,
Really hard to say. Is it repeatable, always 27 times? Is everything else OK, just the LCD acting up?
I think you're going to have to post some code.
