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 occu pied. Virtual serial ports appear to operating system or any Windows application as "standard" hardware serial ports. Virtual serial ports created by VSPD work exactly the same as real ports in your system supporting all signal lines and baudrate emulation. So, there is no need to spend money on hardware null-modem cables or serial port extenders, because VSPD emulates all types of null-modem configurations. For instance, using Virtual Serial Ports Driver you can create two virtual serial ports: COM5 and COM6 in a virtual pair so they can be opened by two different applications. Everything that the first application sends to COM5 will be received by the second application at COM6, and all data sent to COM6 by the second application will be received by the first one at COM5.
