I have command echoing working via the LCS Ser2! Here's the output from a sequence command where the tower requests a full stop, the engine speed is set to zero, and the engineer acknowledges:
[TOWER_SPEED_RESTRICTED ID# 65 Data: 0]
[ABSOLUTE_SPEED ID# 65 Data: 24]
[ENGINEER_SPEED_RESTRICTED ID# 65 Data: 0]
I will add the display of the byte sequence to this output as well.
@Patrick Keistler, @BlueFeather fyi
