Hi All,

I have one Software which accepts data only through COM port. But I want to send data to that software from the PC on which it is Loaded.
So i want to FOOL that software using my program so that that software will accept data as if it is coming from some external Serial device.
IS IT POSSIBLE?
OS is windows 2000 professional
CAN U HELP ME IN THIS...

Thank U
Chinmay

Not sure ... but would a simple "loop back" plug work? They're used to test comms on applications like Laplink where you're not sure if the port is actually workin. Just a case of wiring up a plug with loops.

Cheers,

Chinmay,
This may not be the most elegant approach but if you have two serial ports on your computer, you could use a null-modem cable between them and transmit the data out one port to be read by the program monitoring the other port.

Why don't just connect together the two COM ports of your PC? You can then write a simple program to send/receive data thru COM2 while the other
application will receive/send data thru COM1.
Transparent and flexible, without weird software solutions.

If your PC has no available COM ports you can buy an additional serial card.
