I am trying to incorporate DDE into a  MS VC++ MFC program. The program =
receives serial input, and I want to pass it along to Excel via DDE. As =
soon as I make the first data poke to Excel, my program slows down so =
much I can see each serial port character displayed on the screen one by =
one, instead of a line of data appearing instantly (9600 baud), even =
while there is no more data being sent to Excel. If I break the DDE =
connection, the program resumes normal speed again. Is this typical of =
DDE, or is something wrong somewhere. Or is there some kind of messaging =
continuing between Excel and my app even while there is no DDE data =
exchanges occuring?

Please suggest I use COM only if you have some well documented =
stand-alone VC code examples I can incorporate into an MS VC++ MFC app.

Thanks
John
