According to Wikipedia, a text terminal is "a serial computer interface for text entry and display". It was the principal way of communicating with computers in the 70's. As a Text terminal requires has very basic computing needs, it is quite easy to emulate in software. Text terminal.jpg

For using your atari ST as a Unix/Linux terminal you will need:

  • a serial port, or an USB to serial adpter on your Unix/Linux computer
  • a null modem cable to plug on the serial port of the ST
  • an Atari ST or better with Terminal Emulator software. We recommend to use TAZ.

You can just throw the CD driver away, as Linux has buit in support for these devices. When plugged, you can see it has been recognized using the dmesg command.

Most important to us here is the last line, which tells that the kernel has assigned the name /dev/ttyUSB0 as a serial port.

Start a Linux login prompt on the serial port

Start TAZ on the Atari side and configure it
