Description
The 3Com 3CXM356, branded under the Megahertz line (a 3Com subsidiary known for networking products), is a 56K PC Card modem designed specifically for laptop computers. This device integrates 56K data and fax modem capabilities into a compact form factor that slides into a laptop's PC Card slot. The inclusion of the 'winModem' designation suggests it likely relied heavily on software and the host computer's CPU for processing, a common design choice for cost-effectiveness and performance optimization in Windows environments of the era. A key feature of the 3CXM356 is its Xjack connector. This innovative design eliminated the need for a separate dongle or cable to connect to a standard telephone line; the connector itself could be pulled out from the modem body, allowing direct insertion of an RJ-11 cable. This made it exceptionally convenient for mobile users, reducing the number of accessories required and simplifying setup on the go. Operating at 56K speeds according to the V.90 standard, this modem offered the fastest dial-up internet access available to consumers at the time of its release. It provided essential connectivity for tasks such as browsing the web, sending and receiving emails, and transmitting faxes. Its PC Card Type II interface ensured broad compatibility with laptops equipped with such expansion slots, making it a popular choice for professionals and students needing reliable remote access.
