Feedbacks

# UNRESOLVED: source describes commands that return status but does not specify
# response string formats. Feedback formats not documented.

Variables

# No discrete settable parameters found in source beyond routing commands.

Events

# UNRESOLVED: no unsolicited notification descriptions found in source.

Macros

Notes

Command syntax rules:

Commands are case-sensitive
Command terminators (end-of-line): . ; ! " $ &
Format: [command]X[operator]Y. where X=input, Y=output
Group operations use output groups predefined via G PP W,Y,Z. command

Pinout (9-pin female D):

Pin	Function
2	Tx (Transmit)
3	Rx (Receive)
5	Ground

Memory slots 0–9 store complete input/output route configurations.
