MODEMS AND RS-232

The cable that connects a standard modem to a computer device typically uses the wiring and signaling standard, "RS-232".   The standard discusses the physical and electrical characteristics required for the interconnection.

There are a variety of configurations for an RS-232 cable as well as several common tools used to troubleshoot a problematic connection.  This section of the Compendium discusses the RS-232 standard and several types of RS-232 interconnections as well as explaining how to use a Break-Out-Box to troubleshoot a cable problem.
