Virtual Serial Port ActiveX Control is a powerful tool for professional developers that allows your application to create custom additional virtual serial port in system and fully control it. Created virtual serial port looks like real serial port for other Windows applications. From your application you can control data sent to virtual serial port by other applications and respond to them by sending own data to virtual serial port.
Virtual Serial Ports Driver for Windows CE creates two pure virtual serial ports in your system which are virtually connected to each other. For other Windows applications they are seen exactly as two real serial ports with null-modem connection.
