Null Modem Emulator
Emulate virtual Null-modems
The ports created by this virtual null modem emulator appear to your operating system or any Windows application as standard hardware serial ports. In fact a virtual null modem emulator not only does not clutter your desk, but also works faster than a real null modem. The virtual COM driver can be included in your own software providing a way to create and configure virtual COM ports directly from your application (OEM license).
Any number of virtual COM ports
Real ports settings emulation
All signal lines support
Serial port splittingExact replication of hardware serial interfaces is enabled by this virtual null modem emulator which lets you split a single physical serial port (e.g. Com 1) into multiple virtual communication ports (COM2, COM3, etc.). Virtual Serial Port Driver PRO lets different applications share hardware serial ports. A single COM port and attached device can then be accessed by multiple serial applications.
Joining COM portsThe virtual null modem allows you to link one real physical port to multiple virtual COM ports. Using this null modem RS-232 enables simultaneous data transmission from all connected virtual COM ports to a serial application attached to the real COM port. Essentially, you can now direct data traffic from multiple devices to a single application.
Creating bundle connectionsApplications that work with a finite number of ports can take advantage of one of Virtual Serial Port Driver PRO’s special features. Using this option, called Switcher, you can join multiple physical ports into one virtual port that is used by your application by creating a switcher to the virtual COM. You have the choice of using the same name on all of the ports.
The switcher detects free COM ports from the list of joined ports and offers one to your application whenever it requires a serial port connection. Your program will appear to be communicating through the same port as it takes advantage of any available free serial port.
Switching ports automatically
In case your application is designed to work with a limited number of ports, you can use Switcher, a special feature of Virtual Serial Port Driver PRO. With this option, you can join several physical ports into one virtual (optionally, you can give the same name to all of the ports), and create a switcher to this virtual COM port in the required app.
Whenever your program will require a serial port connection, the switcher will detect a non-occupied COM port in the list of joined ports and offer it to the app. This way, your program will automatically talk to any free serial port as though it were always the same port.
Merging COM portsAll devices and applications can enact simultaneous data exchange with multiple other devices or applications. Any number of physical or virtual COM ports can be added to a single serial port bundle that is not segregated into ‘IN’ and ‘OUT’ sides. One of Virtual Serial Port Driver PRO’s advanced features replicates anything sent to one port to all other real or virtual bundled ports.
