Serial to Net utility for the Pi allows one myServer 6 computer to connect via IP to another Pi where a serial device might be connected. Converts serial port to an IP address
Use case: ELK security panel connected to a Pi4 via serial to USB adapter. myServer 6 running the ELK driver located elsewhere. Optionally you can connect the ELK to multiple myServer 6 instances (for testing as example).
1.) First identify the port name of your serial device. This can be done via the following command from a linux command:
dmesg | grep tty
2.) Install Ser2Net:
sudo apt update
sudo apt upgrade
sudo apt-get install ser2net
sudo nano /etc/ser2net.conf
Append to bottom of the file and save:
2101:raw:0:/dev/ttyUSB0:115200 8DATABITS NONE 1STOPBIT max-connections=3
2101 is the TCP port. Replace with any value that is not already used between 1024 and 65535.
/dev/ttyUSB0 is the port name. Replace with your specific port name per step #1.
115200 is the baud rate. Replace with the baud rate required for the serial device.
max-connections=3 this is so that multiple clients can connect to TCP server.
Resave the file with the original filename (Ctrl O) and then exit (Ctrl X)
3.) Restart Ser2Net:
sudo /etc/init.d/ser2net restart
