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. HW Virtual Serial Port. Wireless remote serial port - through WiFi. HW Virtual Serial Driver is primary designed for HW group devices, but it can. WiSnap™ WiFi Connection to PC using COM-TCP Redirector. Pairs of virtual COM port as. RS-232 interface to an open serial port on. Wifi Serial PortWhen 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.

Virtual Serial Port Windows 10The 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.
