Rcvdump is a demo program.
Rcvdump reads a frame from a MCXPCI COM PORT (set in Asynchronous or synchronous mode)
Rcvdump displays the received frame in Hex & ASCII formats.


The syntax is :
	rcvdump COMx MaxFrameSize

where	COMx is the name of the COM PORT (See mcxsetup program)
	MaxFrameSize is the number of bytes to read


In synchronous mode MaxFrameSize must be set to the framesize upper limit (1024 by default). Each Read
returns a single frame , even if the real frame size is lower than 1024.
