The ADDS 4000 series is a series of text-only terminals with a monochrome screen that came in page-white, amber, or green colors. Named after the manufacturer "Applied Digital Data Systems" (later renamed to Boundless Technologies), they are compatible with PC101/102/106/107 or ANSI VT-220 keyboards via RJ11 connector on the left side.

Connecting to Linux Machine

The easiest way to connect the terminal to a Linux machine — such as a Raspberry Pi — is to obtain a DB-25 male to DB-9 female null modem cable and a DB-9 male to USB adapter cable. You must get one labelled "null modem", as it is cross wired to be used without a modem.

Connect the cables to each other, one end to the terminal's EIA port (fastest), and the other to a USB port on your Linux host device.

Terminal Setup

1. Press Ctrl + Scroll Lock (may be "PrLne" or "PrMsg" on your keyboard) to access Setup menu.
2. Press F1 to enter Quick menu (if not already selected). Set the following:

   Host/Printer=EIA/None (enables EIA port to be connected to Linux host)

3. Press F2 to enter General menu. Set the following:

   Emulation=VT100

   (and optional settings to turn down the bell noise and set a screen saver to protect the CRT)

4. Press F3 to enter Display menu. Set the following:

   Display Cursor=On

   Page Length=24

   Screen Length=26

   Columns=80

5. Press F4 to enter Keyboard menu. Set the following:

   Key Mode=ASCII

6. Press F6 to enter Ports menu. Set the following:

   EIA Baud Rate=115200 (if not available, note the value you choose)

   EIA Xmt=Xon-Xoff

   EIA Data Format=8/1/N

   EIA Recv=Xany-Xoff(XPC)

   EIA Parity Check=Off

   EIA Xmt Pace=Baud

7. Press F7 to enter Host menu. Set the following:

   Comm Mode=Full Duplex

8. Press F9 to enter Emulation menu. Set the following:

   ANSI-ID=VT100 (this will identify the terminal as a VT100 terminal to Linux)

   Status Line=Off (recommended to prevent burn-in with line/text at top of screen)

9. Press F13 (may be "Print" or "Print Screen" on your keyboard) to enter Exec menu.
   • Press Enter on "Save Terminal" and wait for "DONE" message.
   • Press Enter on "Save Session" and wait for "DONE" message.
10. Press F14 (may be "Hold", "Break", or "Pause" on your keyboard) and Y to save and exit.

Linux Setup

1. Enable the terminal console to be accessible by serial.
   • On a Raspberry Pi, this can be set by running sudo raspi-config and enabling the "Serial Port" option under Interface Options; or by running sudo vi /boot/config.txt and adding an [all] section at the bottom followed by enable_uart=1.
2. Enable the USB serial port and set the baud rate to match the one you had set in the previous section.
   • On a Raspberry Pi, you can do this by entering the commands:

     sudo stty -F /dev/ttyUSB0 115200

     sudo systemctl enable [email protected]

     sudo systemctl start [email protected]

3. If a login prompt isn't shown on the physical terminal, reboot the physical terminal followed by the Linux machine and it should prompt you for a login on the physical terminal.
