More information about socat is available on the official website. Installation and configuration are painless, and allows your serial devices and PC to communicate seamlessly over a TCP/IP network. You can now see the socat connection towards the destination IP. NOTE: We install pyserial if necessary (if you go to the previous step we will receive an error): sudo apt-get install python-serial Run it from a new terminal (with ROOT privileges) with the following command: python sender.py

Let’s prepare a simple script to write on serial (using Python) and save it with the name sender.py : #START (serial forwarder) import sys import time import os, pty, serial #configure the serial connections print "\ nSTARTING SERIAL PRINT\n" # open serial port ser = serial.Serial ('/dev/ttyS0', 9600, rtscts =True, dsrdtr =True) print "SERIAL FORWARDER > (remind to use this as a root !)\ n" # write test string ser.write ("\n > serial test for an ALARM! \n go go ALARM! go :) ") # close serial port ser.close () #END When working with terminals on Mac and Linux, you will often see tty used to represent a communication port rather than COM port. On computer 2 (running Fedora as root), I type : pppd /dev/ttyS0 115200 lock nodetach noauth debug 195.0.0.12:195.0.0.13. Computer1 -> USB-Serial Converter -> Serial Cable -> Serial port of Computer 2. We then give the command (in a new terminal with ROOT privileges): nc -l 60001 I'm trying to set up a ppp connection between 2 computers via serial cable, to enable TCP/IP over serial. In order to receive the data, we must prepare a listener on the destination IP address (this is not covered in detail in this article). In our case we simply use netcat, always monitoring the 60001 port (make sure the chosen port is not already in use). Obviously it will be sufficient to modify the command with the desired serial and IP:port address.Īnother possible use is the binding (union) of two different serials: socat PTY,link =/dev/ttyS10 PTY,link =/dev/ttyS11 Open a terminal and acquire ROOT privileges (important).Įxecute this command to initialise the forwarding of incoming packets to the serial port. Socat is a very useful tool that is already present in many Linux distros, enabling you to manipulate and forward network packets.
