This read-only INTEGER reports status information about the modem described by this table entry, such as no internal modem, an installed US or international internal modem, or a serial port that is not set up or directly connected, though only some values apply to any given row. An administrator cares to confirm whether a modem is actually detected versus the port being unconfigured. For example, an admin sees this OID report noInternalModem(2) for the internal-modem row and orders a replacement modem card for that server.
