Microcom Systems was a major modem vendor during the 1980s.  They hold an important place in modem history due to their introduction of the MNP error-correction and compression protocols, which were widely used under license by most modem manufacturers in the 1990s.   Microcom introduced their own modems starting with the AX/1200 and AX/2400 modems, which featured MNP 4 error correction in an otherwise standard 1200 bit/s Bell 212/v.22 or 2400 bit/s v.22bis modem. When a Microcom modem was used by both ends of a connection, the connection was entirely error-free.

Microcom continued developing the MNP standards, and later introduced the MNP 5 standard, which compressed the data in the modem before sending it, thereby actually increasing the data rate while still being error-free. MNP 5 was introduced on the AX/1200c and AX/2400c, the "c" for "compression". MNP 1 through 5 were later handed to the ISO for standardization, and became widely available.

Microcom introduced a series of ever-faster modems, typically based on newely introduced standards. The first of these was the 9600 bit/s v.32-based AX/9600, but the introduction of v.42bis compression system that easily outperformed MNP 5 led them to introduce the QX/4232, followed by the 14,400 bit/s QX/4232bis when the v.32bis standard was ratafied. Microcom and Rockwell became partners on a number of ventures, including the creation of the MNP 10 and MNP 10EC protocols, and Microcom increasingly used Rockwell chipsets across their line.

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.  Compaq purchased the company in 1997.
