Compaq 317933-B22 56K V.90 PCMCIA Fax/Modem Card

Product Description

The Compaq 317933-B22 is a portable 56K V.90 PCMCIA Fax/Modem Card, designed to provide essential communication capabilities for laptop users on the go. This external card slides into a Type II PCMCIA slot commonly found on laptops from the late 1990s and early 2000s, offering a convenient way to establish dial-up internet access or send/receive faxes using a standard telephone line. Adhering to the V.90 standard, the modem supports data download speeds of up to 56 kilobits per second, which was the maximum achievable speed for dial-up connections. It also includes fax capabilities, operating at speeds up to 14.4 kilobits per second. The card supports various data compression and error correction protocols, such as V.42bis and MNP, to optimize performance and ensure reliable data transmission over potentially noisy phone lines. Its PCMCIA interface makes it hot-swappable, meaning it can be inserted or removed from the laptop while the system is running, offering flexibility for users who frequently move between wired and wireless environments or need to connect to different networks. This modem was a crucial accessory for business travelers and remote workers who relied on dial-up connectivity for email, internet browsing, and faxing before the widespread availability of broadband internet.
