| `-port` | (required) | Serial port on master UART (GPIO2/3 adapter) |
| `-baud` | `921600` | Must match firmware `UART_BAUD_RATE` |
Implements the VERSION command (`MessageType` = 3): sends framed `03`, decodes protobuf `UartMessage.version_response`.
### Commands
| Command | UART payload | Description |
|---------|--------------|-------------|
| `version` | `0x03` | Prints `version` and `git_hash` from firmware |
| `clients` | `0x04` | Lists slaves registered on the master via ESP-NOW |
`clients` requires slaves to have responded to master discover broadcasts first.
Example output:
```
clients (2):
[0] id=42 mac=aabbccddeeff ver=1 available=true used=false last_ping=12345 last_success_ping=12345
