// The AT command parser for the serial interface.


// AT commands we'd like to have:
//
// AT+Freq? -- get the frequency
// -- <value> -- current frequency
//
// AT+Freq -- set the frequency
// -- OK -- response
// <data> -- frequency value
// -- OK -- response
//
// AT+SF? -- get the spreading factor
// -- <value> -- current spreading factor
//
// AT+SF -- set the spreading factor
// -- OK -- response
// <value> -- spreading factor
// -- OK -- response
//
// AT+BW? -- get the bandwidth
// -- <value> -- current bandwidth
//
// AT+BW -- set the bandwidth
// -- OK -- response
// <value> -- bandwidth value
// -- OK -- response 
//
// AT+RXDEQ? -- Dequeue the RX queue
// -- <value> -- RX frame 
//
// AT+RXCNT? -- get the number of RX frames waiting in the queue
// -- <value> -- number of RX frames
//
// AT+RXCLR -- clear the RX queue
// -- OK -- response
//
// AT+TXENQ -- Load the TX queue with another frame
// -- OK -- response
// <data> -- TX frame data
// -- OK -- response
//
// AT+TXCNT? -- get the number of TX frames waiting in the queue
// -- <value> -- number of TX frames
//
// AT+TXCLR -- clear the TX queue
// -- OK -- response
//
// AT+NVS -- save settings to Non-Volatile Storage (NVS)
// -- OK -- response
//
//
