Additional Modem Information

Integrated Remote Console (IRC) has been tested and is compatible with a wide variety of internal and external modems. IRC requires a high-speed (14400 baud or greater) Hayes-compatible serial modem. Virtually all external RS-232 serial modems meet this requirement.

Modem Types

Internal modems must be ISA and must be controller-based. The following sections describe many of the commercially available types of modems and their compatibility with IRC.
