;Example program showing how to use some of the commMg3.au3 UDF functions
;this example is a very simple terminal
;Version 2 26th July 2006
;changes-
;change flow control checkbox to combo and add NONE
;correct error in call to _CommSetPort - stop bits were missing which meant th eflow control was used for stop bits
;Dec 2013 - correct setting of Parity and flow, thanks to MichaelXMike
