RetroModem Bridge is a Windows serial-to-TCP modem bridge for vintage computers. It lets a machine such as a TRS-80 Color Computer, Commodore, Apple II, Atari, Amiga, or DOS PC use a serial connection to dial Telnet BBSes with Hayes-style ATDT commands. Version 3.4 also adds an experimental Local Door Game Mode. This lets the retro computer dial a local door game alias, such as ATDT USURPER, and RetroModem Bridge launches the configured door game on the Windows PC.
