Program monitors com port. If Com port sees a string
aD0!
it will send back
10+65.55+72.5+1013.20<CR><LF>
So I will use hyper terminal to send the Command aDO! and should get back the
string 10+65.55+72.5+1013.20 with a CR and Line feed
Program should be able to select Com Port to monitor and have a graphical
front end to see the incoming command it is responding to
