Connecting GX2100 to pican-m

[DG3612]

Just out of curiosity, what happens when you plug that RS422 converter back into your PI and look at that port? You could do it with "cat /dev/tty<whatever the port is>". The reason I ask is that I"m wondering if the chunking you are seeing is actually a Windows thing rather than the data coming out of the SignalK server.

Keen idea, but I do not have any more serial ports available.
I believe it has to do with some send buffer size configuration.

The same happens when I create a serial connection directly in openCPN.
Do both programs simply do not flush the send buffer after each sentence?
But can that be? Serial communication might be relatively new to signal-k but its mature in openCPN.
