Virtual Serial Ports

Suppose your PC has 2 serial ports: COM1, COM2. Suppose you need to let your program user see a COM3 which you want to redirect (e.g. you want to send the output strings of this virtual COM3 through the Ethernet card and to to read in the COM3 receive buffer what is coming from the Ethernet card). Does anyone know how to provide such an "illusion" (COM3 does not physically exist but a serial communication program can use it)???
Thanks in advance!

ups...


anyone help?

It's fairly simple in assembly (just create a COM3 driver), but it probably can't be done in VB. There are freeware programs you can use if you just need the function, as opposed to your wanting to learn how to do it. Check out SerProxy http://www.lspace.nildram.co.uk/freeware.html
