Modem & BBS

FujiNet emulates a classic Hayes-compatible modem, allowing any terminal software that supports a serial modem to connect to modern Telnet-based BBSes and other services — no phone line required.

How it works

FujiNet translates AT modem commands into real Telnet connections over your Wi-Fi network. Your terminal software thinks it's talking to a real modem.

Compatible terminal software by platform

  • Ice-T XE — Full-featured terminal with ANSI color support
  • BOBTERM — Popular Atari terminal program
  • Flash — Fast terminal with many BBS features
  • DeathBaud — Modern Atari terminal supporting FujiNet modem
  • Z-Link — Full-featured Apple II terminal

Connecting to a BBS

  1. Launch your terminal software and configure it for the modem port.
  2. Set baud rate — FujiNet accepts any baud rate (it auto-negotiates).
  3. Dial using the AT command: 
    ATDT bbs.fozztexx.com:23
  4. FujiNet translates this to a Telnet connection and returns CONNECT.

ANSI art

Many BBSes use ANSI escape codes for color art. Use a terminal program with ANSI support (like Ice-T XE on Atari) for the full experience.

Phonebook / speed dial

FujiNet's modem emulator maintains a phone book of saved BBS addresses. Access it via CONFIG → Modem to add, edit, and organize your favorite BBSes. Then dial by number:
