Anything over 8000 resets the unit I'm trying to program

Yes it says Serial2 Errors occurred framing 0 parity 0 overrun (various no's as it retries) and break 0. Hope this means something to you I've no idea

The program I'm using is a programmer. The unit in question goes into program mode but I'm unable to send and data to it, any ideas. Hal your patch did improve things slightly before your patch I couldn't even get program mode

How do you configure a com port if its to be used with a null modem cable?
