Virtual Serial Port Kit creates a pair of virtual serial ports connected with virtual null-modem cable. The software provides null-modem connection between two serial communications applications. Communications software interacts with each other via virtual COM-ports in the same way as via hardware COM-ports connected with real null-modem cables.
All the data written to one virtual COM port can be immediately read from another one and vice versa.
Once created, virtual serial ports appear in the list of COM port devices on your computer and function as hardware serial ports.
As soon as any serial application opens the first virtual COM port and the other application opens the second virtual COM port, the connection between two serial applications is established. Now serial data can be transmitted over virtual COM port connection.
Virtual COM ports fully emulate behaviour of hardware COM ports, so any serial communications application works with virtual COM port as if it was a hardware COM port.
The program makes virtual serial ports accessible at every system startup even prior to user's logon. Once configured, virtual COM ports are created automatically and you don't have to adjust anything or even login to operating system.
There are several common pinout schemes of null-modem cables used for the communication process. Virtual Serial Port Kit supports different null-modem pinouts with different handshakes allowing also to customize them.
A loopback plug is a device used to test serial communications applications. As data is looped, the application recognizes output data as input data. Using Virtual Serial Port Kit it is possible to emulate loopback plug just in few clicks.
There are serial application A and serial application B on the computer. You need to establish bidirectional connection and data transmission between these serial applications. Virtual Serial Port Kit creates virtual serial ports COM2 and COM3. The virtual COM-ports are connected with a null-modem cable and appear in the system as usual hardware COM ports.
The application A occupies COM2 and application B occupies COM3. As soon as the applications open COM2 and COM3, two-way data exchange will be established.
Virtual Serial Port Kit functionality can be easily integrated into your application. So you can create virtual serial ports and connect them via virtual null-modem cables from your application directly. Read more…
"...tried three shareware programs. One worked fine with Hyperterminal, but not with the two our programs. The other was too complex, too expensive, and offered features we didn't need. But Virtual Serial Port Kit satisfied our needs completely."
