Short description of UDP Serial Port Redirector 1.2.1: The Haxxio UDP Serial Port Redirector is the missing link between devices that speak UDP on your network and are thus " connected" to your PC, via an Ethernet port (specifically UDP over IP) and Windows applications on the PC that can only talk to a serial port. Most applications for the Redirector are based on one of replacing a simple serial cable, or connecting serial devices over WiFi links, or enabling groups op PCs to communicate together.
