In many applications, there is a software that must connect to a device via serial port. To make this possible download com0com and install it on your PC. Create a pair of virtual ports choose one of them as the serial port in 'dihav SerialPort over WiFi” software and select other in the software that controls your device.

Contents • • • • • • • • Overview [ ] The purpose of the redirector is to make the virtual exhibit behavior that closely resembles that of a 'real' COM port, i.e., a COM port driver for local hardware. A virtual COM port itself is a relatively simple software mechanism that can be implemented by driver software similar to that of a conventional COM port driver. The main challenges arise in two other areas: the network connection to the device server and the behavior of the device server.

These issues are described in the Technology section below. Applications use a COM port redirector through one or more virtual COM ports that the redirector creates, as configured by the user. When the application opens the virtual COM port, the redirector makes an network connection to the device server at the specified IP address and TCP/UDP port number that corresponds to the remote device on the server. The COM port redirector then begins relaying the application data stream between the virtual COM port and the device server. A redirector will typically permit creation of many (at least 256) virtual COM ports, but simultaneous use of hundreds of ports is often practically limited by a number of factors, including the memory and processor requirements of the redirector, limits on operating system resources, and the performance of the network stack. A redirector for the Windows operating system is typically configured using a control-panel style graphical user interface for creating virtual COM ports, configuring settings for individual COM ports, and configuring global settings affecting all COM ports.

The redirector GUI typically also includes displays of virtual COM port activity and various diagnostic aids. The performance of a COM port redirector is determined by both its implementation and the network it uses to reach device servers. The performance drawbacks of simple redirector implementations can be largely addressed by kernel-level drivers that avoid context switches. Network packet loss or excessive packet times have dramatic effects on redirector operation and must be avoided. COM port redirector software products have been offered by at least 30 vendors dating back to the early 1990s. Compatible networked device servers are currently available from a large number of manufacturers, with a heavy concentration of revenue in the top players, who are based in the North America and Asia/Pacific regions.

The equivalent software for a / operating system is commonly called a tty port redirector and most of the information on this page also applies to it.
