Thanks for that but it did not work to take a guess. Had to follow you advice and look in the datasheet :-)
I enclose the correct PPS code here in order not to lead anyone else on the wrong track.
At this point i can see the loader responding with device name and loader version.
However when actually using "write" it stops after a few characters. I tried 9600, 19200 and extending the TX enable delay.
Enclosed is the output from the GUI.
When I probe(screendump enclosed) the output pins for TX(yellow) and TXEN(blue) i get some funny results. It looks like TXEN goes low long before the transmit is finished. When examining your code i cannot see how that could happen.
Do you recognize the behavior above?
Thanks for your patience.
