I did some more searching and finally found a PDF for the protocol. If you had this link already, shame on you for not posting prior to whole discussion as it would have made things 1000% easier. ;-)

I presume you are referring to this PDF...

Inside this PDF, you should see pages 28-29 which outline the Select System Parameters Setup and you will see that they do allow you to turn off the XON/XOFF handshaking (it is on by default).

If you do this, then you should not have to worry about any flow control (your coding will get alot easier as you don't have to embed XON/XOFF control characters in your messages) when you disable flow control, you should set Flow Control to None in Windows for use with Hyperterminal.

And, after you disable XON/XOFF, you should start seeing that Serial.match() is returning data as you would expect. :-)
