net2tty - simple network to RS-232 bridge

Table Of Contents



1 Introduction

net2tty is a program that takes data from a TCP service on a TCP/IP network, and sends the output of that service to a serial port. It takes output from the serial port and sends it over the network.

2 Download Instructions

Download it here : net2tty.tar.gz

Untar it, and type make.

2.1 Building on RedHat 6.0

In asy.c, before the #include <termios.h>, insert a line #define __USE_MISC

I haven't tested that the code works after doing this, but it compiles.


3 Running it

net2tty on its own with no options will give this help screen:
