A need for additional serial ports may arise when you cannot connect your legacy apps to serial equipment because there are not enough serial interfaces in a computer to attach all the required devices. In this case, the solution would eventually become creating virtual COM ports and sending data over them.
Virtual serial connections play one of the key roles in the process of managing remote serial interfaces. Once you create a virtual serial port, you can share it over TCP/IP, LAN, WiFi or the Internet so that any remote computer or device can connect to it wirelessly over any distance.
The simplest way to achieve this is by using a dedicated third-party solution like Eltima Port Virtualization Technology (EPVT) that will help you create virtual RS232, RS422, RS485 interfaces in any quantity.
For instance, you may need to establish a serial communication between a COM port device and a serial app running on a server computer but have no free interface on the machine. All you need to do is integrate Eltima Port Virtualization Technology directly into the software program and hardware device. The technology will create a pair of virtual COM ports linked by a virtual null-modem cable and the serial communication will become possible. No additional hardware converters, wires, or cables are required. The dedicated technology will make your software and equipment talk to each other across the network.
One of the main advantages of this type of communication is that the distance between serial devices and computers does not matter. Whether your remote equipment is in another office, city, or country, you’ll be able to connect to it fast and securely.
The really great thing about this highly flexible technology is that it can be customized according to the needs of virtually any serial product: software or hardware.
