Solved Uart on Duet3 io0

[gtj0]

I've been trying to use Duet3 io0 as a uart to connect to the SBC for diagnostic purposes with M575 P1 B115200 S2 (raw mode). With this I can send commands from the SBC's serial port to the Duet3 and they get processed correctly but I get no data back. Should this work?

I haven't tried Mode 1 (PanelDue mode) because I didn't want to have to calculate the checksums but I'll try that next.

You have to ask for the response like PanelDue does, using M408. In RRF 3.02 there will be an option to have responses sent directly.

@dc42 Ah OK. I'll give that a try.
