Virtual Serial Port Driver is an advanced utility, which emulates unlimited number of RS232 serial ports connected via virtual null-modem cable using special driver, which can be easily included in your own software providing simple and convenient way to create and configure virtual serial ports directly from your application.

In other words, with Virtual Serial Port Driver you can create any number of pure virtual serial ports in your system connected into pairs via virtual null-modem cable without having real serial ports occupied. Virtual serial ports created by VSPD work exactly the same as real ports in your system managing all signal lines and emulating baud rate.
