Send: F0 7D 11 02 00 03 F7
- Logs GET for TG 2 param 0x0003, queries value, logs result.

Send: F0 7D 01 20 00 04 00 40 F7
Send: F0 7D 21 01 00 04 00 40 F7
- Logs SET for TG 1 param 0x0004, updates value, logs result.
6. Get All Parameters for TG 0
Send: F0 7D 00 10 F7
Send: F0 7D 11 00 F7
- Logs and dumps all TG 0 parameters and values.
7. Malformed or Unknown Parameter
