"We are using Virtual Serial Port Driver for testing out Geographic Information System software connectivity with a virtual GPS (software simulation). The GPS emulator is simulating the output we normally receive from a GPS navigator."

Complete emulation of real serial ports

Sometimes you may need to use more serial ports than are physically available in your system. An easy way to add more COM ports is using Virtual Serial Port Driver, which creates virtual serial ports and a virtual null modem cable for each pair of them (which connects two virtual serial ports to each other).

This software solution works smoothly, allowing you to emulate as many serial ports as you want while supporting all the settings and signal lines as if those were real COM ports.

VSPD offers you a number of advantages:

Easy way to add more COM ports in the system

The solution is software-based, so you don't have to tackle extra cables and occupy real COM ports. Virtual serial ports fully emulate real ones, so that an application communicating with a virtual port never suspects the difference. Moreover, using virtual ports is often more convenient than using real ones since virtual serial port connection offers unmatched stability.

Unlimited number of serial ports

The good thing is that Virtual Serial Port Driver can create as many pairs of virtual serial ports as required: whenever you need, just add another pair of virtual ports, connected to each other via virtual null modem cable. Any data sent to a virtual port is automatically copied to the other port in the pair.

Full emulation of real COM port settings

Virtual serial ports created by Virtual Serial Port Driver are indistinguishable from real ones, so any application that need to communicate via serial interface can use virtual COM ports for that purpose.


Each pair of virtual serial ports supports all hardware signal lines and allows you to set any type of line connection, which is quite useful, especially if some application demands special options of signal line connection.

If your application requires fixed speed compatibility, you will fully appreciate baud rate emulation offered by Virtual Serial Port Driver.
