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!

Re: Virtual Serial Ports
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
The most difficult part of developing a program is understanding the problem.
The second most difficult part is deciding how you're going to solve the problem.
Actually writing the program (translating your solution into some computer language) is the easiest part.
Please indent your code and use [HIGHLIGHT="VB"] [/HIGHLIGHT] tags around it to make it easier to read.
