Serial to Network Proxy (ser2net) SourceForge Logo

ser2net provides a way for a user to connect from a network connection to a serial port.  I tried all the other ones I could find and found them lacking, so I wrote my own.  It provides all the serial port setup, a configuration file to configure the ports, a control login for modifying port parameters, monitoring ports, and controlling ports.

The ser2net SourceForge project page contains the source code, among other things, for ser2net.  See that page for more info.

The JUPS project can use ser2net for remote (or local) control of a serial port UPS from Java.
