/*------------------------------------------------------------------------Monitor.h
 *
 * The pourpose of the monitor is to interpret and dispatch data The idea is to 
 * try to set up a relatively flexible interpreter for data coming in from the 
 * serial port and also commands coming from the usb port. Using a jump table which
 * is populated by other modules who register the action to be taken. 
 *
 * ------------------------------------------- current vocabulary.
 * Deal with multi line data.
 * SOD[  :]Start of multiline data
 * EOD[  :]End of multiline data
 *
 * Log file and disk commands
 * DIR[?  ] directory of the disk.
 * TYP[?  ]<fname> type file
 * DEL[ ! ]<fname> delete file
 * DDS[?  ] dates from logs.
 * DMP[ ! ] dump all logs [in order]
 * 
 * DVP[?  ] device is present?
 * DID[?  ] ssn of device?
 * DVT[?  ] timestamp for last device contact.
 * 
 * LOG[ !:] <data line> log data to current log file
 * LSV[? :] logger software version
 * LTS[ ! ] sync time with client
 * LNT[ ! ] sync time from network.
 * LTM[? :] logger rtc time
 *
 * TX2[ ! ]<text sent to radio on tx2>
 * NSC[?  ] network scan
 * NPW[ ! ]<passwd> network password
 * NJN[ ! ]<ssid> join network.
 * NST[?  ] network status.
 *
 * PFD[?!:] pachube feed
 * PKY[?!:] pachube key
 * PIP[?!:] pachube server ip
 *
 * TS[1-5][ :] temp data sent to pachube
 * TPT[ ! ]<data> test data sent to pachube slot #1
 * FAN[  :]<fan setting>
 * CHL[  :]<chiller setting>
 * STC[  :]<state#> <Description> state changes sent to pachube (slots #6 and #7)
 *
 * SSV[ ! ] save settings (read	 bom5k.set)
 * SGT[?  ] get settings  (write bom5k.set)
 * 
 * all remaining items are sent to the monitored device
