Hyperterminal

HyperTerminal is a terminal emulation program originally bundled with Microsoft Windows operating systems from Windows 95 through Windows XP. It allowed users to connect to remote computers, routers, switches, and embedded devices using a serial port (RS‑232), modem, or Telnet. While discontinued after Windows Vista, it remains a notable piece of legacy software for hobbyists, industrial machine maintainers, and retro-computing enthusiasts.

The software functions by establishing a connection through a PC's COM (serial) port or over a network. To communicate effectively, the user must configure specific transmission parameters to match the connected device: hyperterminal
