Hi JD,
looking at your code cannot answer Gambit's question, because his
question relates to the run-time of your program. I will re-phrase it:
Are you sure that some other computer is actually _sending_ something
to the port you're reading at?
Here is what I would try out:
- Connect your COM port to whatever source you have (if you have a
null modem cable this could well be the second COM port of your
machine).
- Start HyperTerminal on _your_ COM port.
- Get your source to send something - do you see the data arrive in
HyperTerminal? If not, you have to fix your setup until the
communication works.
Hint: If your ports are connected with a null-modem cable something
easy as "copy c:\autoexec.bat COM2:" can be really useful.
- Note the state of the handshake lines. (You do have this device
which lots of LEDs to show the current state of each line? If you
don't have it: run - don't walk - out to get one - they are life
savers.)
- Back in your program: Make sure the handshake lines have the exact
same state as noted when working with HyperTerminal.
- Repeat whatever you did to send something to HyperTerminal - your
program should receive it now.

Final hint: I would try at first with a null-modem cable and 
	"copy c:\autoexec.bat COM2:"
Until you get this to work there is no point in trying anything else.
