Commands to the WxDux & responses
The WxDux sits on the serial port it listens for and responds to ASCII text sent to it and returns text. This can be seen by starting Microsoft's Windows application HyperTerminal. Use 9600 baud, no parity and no flow control. Use of flow control will completely halt any communication with the WxDux.
Send (case sensitive). Do not send the quote marks, just the letter.

All sensors are pre-calibrated and do not require recalibration with normal operation.
How to Talk to the Temperature Software:
"T" gets temperature in C and F in the format CC.CC(FF.FFF)
"H" gets Humidity in %
"L" gets Light Level (zero is dark, 100 bright)
"F" gets Air Flow. Still air is about 10, rushing air is about 200
"0", "2", "4" get condition of 3 contact closure sensing, 0-closed, 99-open
"@" gets the internal unique serial number
"X" cycles through and changes the baud rate
"B" begins auto transmission of the entire data string every three minutes
":" turns the internal LEDs off
"<" turns the LED #1 on
">" turns the LED #2 on
"V" set verbose move on
"v" sets verbose mode off
NOTE: sending a "B" gets a complete string of data such as "67.8, 23.4, 43, 34, 99," which translates to:
Temperature = 67.8F (23.4C)
Humidity = 43
Light level = 34
Contact sense 1 = 99
Contact sense 2 = 99
Contact sense 3 = 99
