Serial port loopback help

com port loopback

Hi,
I have one application which must sends data on the serial port (com1) to another application which receive data from the other serial port (com2). This system was easy on a desktop PC, with two serial ports available, a simple rx-tx loopback between the serial ports solved the problem. But now I need to do the same thing on a laptop (with winXP). Unfortunatelly, the com2 is internally wired to the IrDA adapter and is not available on a external connector. Only the com1 is. Now, my question is, are there any applications available which helps me to make an internal (somewhere at the windows core) connections between those two com ports?
Thanks,

Why do you need to pass data thru the serial port for transferring the data? You can transfer data within two applications by using files on the Hard disk. Have you tried that?

Nope, it is not possible. One application is made by me, I can do whatever I want with it, but the other application is a GPS navigation software, and I can supply it with data only on the serial port.
Anyway, the sollution is here, thanks to dainis.

that guy changes some windows inf-files so that a connected IrDA-receiver appears as usual COM-port, circumventing the windows IrDA stack. Now you could use a simple adapter (e.g. Vishay TOIM4232 + TFDU4xxx + MAX3232) to connect your or the GPS device via "IrDA-COM-port". Just an idea ....
