Create virtual COM port pairs (serial port pairs)

With duplAxe, you can make a pair of virtual serial ports (VSP pair) "virtually connected to each other" in your system. A virtual serial port appears to application software as a "standard" MS Window's communications port (virtually identical to an RS-232 port). Data may be written to VSP by applications, and data may be read from VSP as though it were a standard COM port. Entering VSP pairs, you can create and use "a VSP pairs pool". The pool of VSP pairs can be used to supply any MS Windows application with serial ports as though they were standard serial ports and physically connected in pairs. This feature is available after installation of the corresponding driver included in the package. This allows MS Windows applications to generate or consume data to and from VSP as though the data were being processed by physical hardware.

duplAxe can be used for sending and receiving data between two separate MS Windows applications running on your PC, thus connecting one application to another by using a VSP pair (for example, Comport and HyperTerminal). Also, you can use the tracing utility, XVCTRC, to document the virtual serial port traffic between your software applications that communicate with such a VSP pair channel (e.g., for application development testing).

After you configured duplAxe, you can launch your software VSP applications to use the settings. For example, you could configure one HyperTerminal as "connected" to COM6 and another HyperTerminal as "connected" to COM17 respectively, and configure duplAxe with the COM6<==>COM17 pair in the Existing Virtual Serial Port Pairs box. Because the duplAxe driver considers virtual serial ports in pairs as "physically connected", these settings would get both HyperTerminals "connected" to each other (through duplAxe), so all you type in the first terminal will appear at the second one.

If you configure Comport as "connected" to COM6 and HyperTerminal as "connected" to COM17 respectively, these settings would get HyperTerminal "connected" to a TCP/IP network (through duplAxe and Comport), and so you could "chat" with remote PCs on your network. Another example is when you use Comport instead of HyperTerminal (thus connecting two networks or same with the "COM6<==>COM17 connector").

You can transfer files with any data or control commands through such virtual serial flow connection. You can configure the virtual serial ports to the maximum speed value MS Windows allows.
