wconsd is a single, simple, Windows program that turns any PC into a telnet to serial server. Using this program, you can access any serial port on the PC over the network.
When I found wconsd wconsd-0.1 it had been unchanged for several years and it originally came from somewhere else (wconsd.c) some years before that. I have fixed some bugs I found and as well as cleaning up the code I am slowly improving on it to make it more widely useful.
Version 0.2.6 has a binary transmission mode
