If you work on a machine that doesn't have a real COM port and need to transmit some data from this machine to another one via COM port, you will need virtual serial ports to achieve your goal. Another possible issue is when you need to emulate your device and make it communicate with some program via serial port. Virtual Serial Port Driver by Eltima has a solution for you. It creates any number of pairs of virtual serial ports connected via null-modem cable. As a result, all the data sent to one virtual serial port can be immediately read from the other one, and vice versa. These ports operate in the same way as real serial ports connected via real null-modem cable, the only difference is that you don't have to physically connect ports with a cable. So everything is performed in a more professional, compact way.
Virtual Serial Port Driver allows configuring virtual ports settings directly from the application or HyperTerminal at any side of the connection. It saves your time, money and efforts, as the connection between virtual serial ports is much faster and more secure than real null-modem connection.
VSPD by Eltima is operating as a system service. Configured, virtual COM ports are available at each system startup automatically.
You can use Virtual Serial Port Driver solution by Eltima as a base of your own software (you will need to obtain OEM License). Since version 6.9 our drivers successfully passed Microsoft Windows Hardware Quality Labs (WHQL) tests and are digitally signed by Microsoft now. The new version offers you Windows Vista Server 2008 and Windows 7 support.
