## SatCam commands
UART at 9600 8N1; case insensitive, delimiter is `SATCAMERA:`, end of line is `{` or `<CR>` or `<LF>`.
The module monitors RXD line when idle and looks for `SATCAMERA:` identifier. Expected commands are for SSTV, PSK and CW systems. Other commands (CAMCFG and DEBUG) are protected by a PIN. User PIN can be set to a custom number, master PIN is fixed for the particular module (computed from the MCU unique ID). It is possible to send protected commands for the next 15 minutes after the AUTH command with a correct PIN. Master PIN can be read using `psk.nvinfo` and `debug.status` commands in case when the user PIN is not set (i.e. is zero).
