Oki PC24M 2400 Baud External Modem With AC Adapter

Product Description

The Oki PC24M is an external modem designed to provide basic data communication capabilities at a speed of 2400 baud. Unlike internal modems that install directly into a computer's expansion slot, this unit connects to the computer via a serial port (typically RS-232) and requires its own power source, supplied by the included AC adapter. This external design made it a versatile option, allowing it to be used with a wider range of computers, including those that might not have available internal expansion slots. Operating at 2400 baud, this modem is significantly slower by modern standards but was typical for asynchronous communication in the early days of personal computing and dial-up networking. It would have been used for tasks such as connecting to bulletin board systems (BBS), remote terminal access, or simple point-to-point data transfer between two computers equipped with similar modems. The Oki PC24M likely features standard modem command sets (like Hayes AT commands) for control and status monitoring, along with LED indicators on the front panel to display connection status, data transmission, and other operational states. It represents a foundational piece of communication hardware from an era when remote connectivity was a specialized and relatively slow process.
