The Haxxio UDP Serial Port Redirector is a system tool that allows applications that are coded to communicate using the serial port on a PC to instead communicate with a virtual serial port, which is exposed on the local area network.

The Examples section shows a number of ways in which this is useful.

However, a word of caution is required - serial communication is prone to errors, and adding additional layers as the Redirector does increases the possibilities of data loss or corruption. Any serial protocol used for any purpose should have at the least some form of checksum mechanism, and packetization, so that the receiving application can be sure that it received the data uncorrupted. An application that has these protections will not be compromised by using a virtual serial cable, as the Redirector provides, rather than a real physical serial cable.
