A program that simulates a serial device to test my code?

[SandiegoSSD]

Hi guys,i'm looking for a program that can simulate a serial device, so that when i run my code, which sends data thru the COM port, I can see what's being sent out of the COM port without an actual device connected to my computer.
I've been searching for such programs.Now my question is what would you call such a program?? a Serial port emulator? or Virtual serial port emulator?

I kinda remember someone else used Hyperterminal to do things like this(i may be wrong), but it's not supported in Win7 any more. Any suggestions appreciated.

Com0Com at Sourceforge is one , there is another I have used, if I remember the name I will add it to this post with an edit.

It seems Hyperterminal doesn't act as a virtual device that works with a program sending bytes. Instead what it does is it sends/receives data with an external device connected to the COM port. Am i right?

I am not aware of any program that will actually pretend to be a com port. The simple way to test a serial program is 2 use 2 com ports and connect one to the other with a null modem cable then point your program at one port and a program like hyperterm or other such com program to the other port assuming of course you have to com ports to work with. If only one port then another pc to act as the device using a null modem serial connection between the 2.

Thank you DataMiser I think i'd probly use 2 computers

Here is the link for the second option I mentioned

the download is Virtual Serial Ports Emulator and is easier to use than Com0Com in my opinion.
