+// 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

+// -- <value> -- number of TX frames
