[1][4] In the mid-1980s several companies introduced new modems with various "high-speed" features in order to differentiate themselves from the growing legion of Hayes 1200 bit/s clones that were flooding into the market.

Developing such a protocol was not all that easy, and generally required a fairly powerful and expensive microcontroller to handle the modulation.

The company also broadened its line into different price points, offering the DeskPorte series as their primary desktop modem, the OfficePorte which was similar but added fax capabilities, and the TravelPorte or TravelCard series of PC Card-based products for portable users.

Microcom also had a range of other products including the award-winning Carbon Copy remote control and file transfer software,[5] LANlord desktop/PC management software, Microcom Bridge Router (MBR), a centralised dial pool system High Density Modem System (HDMS) which was used by service providers for the first deployments of dial-in ports for the early adopter internet and bulletin board users, and LANexpress, a corporate remote access solution.

As other companies increasingly used the MNP protocols, many chose to keep the original commands specified by Microcom, notably AT&T Paragon's chipsets which were fairly popular in the early 1990s.

In 1993 Microcom settled a lawsuit against them by Spectrum Information Technologies via a consent decree that resulted in "a cross-licensing agreement for patents.
