It sounds like you’re looking for information about running Procomm Plus (the classic telecommunications and terminal emulation software) on Windows 11.
Here is a direct, useful breakdown of the current situation, compatibility, and alternatives.
Procomm Plus was a dominant terminal emulator and script-driven communication package from the 1980s and 1990s, used for BBS access, modem control, and industrial serial device management. While obsolete, it remains in use in legacy industrial systems (CNC, medical devices, PBXs) and among retro-computing enthusiasts. Windows 11’s deprecation of the 16-bit subsystem (NTVDM) presents a critical barrier.
Research Questions:
If you own Procomm Plus 4.8 or 5.0 (32-bit), you can attempt a native install on Windows 11.
Tweaks required:
Common failures: Even if it launches, you may hear the modem dial but never connect. Windows 11’s USB stack adds latency that Procomm Plus’s timing-sensitive scripts cannot handle.
