Here is a simple overview of the IBM 3101 ASCII Display Terminal, just covering the basic history, provenance, and its functions. This is not intended to be a analysis, teardown, repair guide, or history lesson on the product mentioned.

Here are the commands used in the video:

Used to find ibm3101. If it don't exist, then find guides to make a ibm3101 terminfo. ls /usr/share/terminfo/i/ibm* ls /usr/lib/terminfo/i/ibm*

Spawns a agetty instance using ibm3101 terminfo if it exist. agetty -n -h 9600 ttyUSB0 ibm3101

These just makes sure that the service works. sudo systemctl status serial-getty@ttyUSB0 sudo systemctl enable serial-getty@ttyUSB0 sudo systemctl start serial-getty@ttyUSB0 sudo systemctl stop serial-getty@ttyUSB0

Copies a base serial-getty service to the recently spawned service. sudo cp /usr/lib/systemd/system/serial-getty@.service /etc/systemd/system/serial-getty@ttyUSB0.service

Open the copied service and paste this block:

NOTE This is the DIP switch setup that works with operating the terminal as a serial device:
