Termnetd (aka termpkg apparently) is a cool little application that lets you stream serial port data over the network. It's a terminal server daemon that exposes the serial port and tty devices directly to a network port.

First Get the repository, execute the configure script, change directory to the platform detected and run the make command:

git clone git@github.com:carlos-jenkins/termnetd.git
cd termnetd
./configure
cd linux
make

Once installed, the configuration file, /etc/termnetd.conf, can be edited to configure which serial port maps to which network port. It can be used to set serial port connection settings as well. The format is as follows:

<IP port>:<state>:<device>:<termios options>;

Example:

3000:on:/dev/ttyS0:B115200 CLOCAL IGNBRK CRTSCTS CS8 CREAD;

Start termnetd by running from the command line:

termnetd

From another terminal use telnet or netcat to receive the data

nc localhost 3000
