# airport-modem(1)

Modem monitoring and hangup utility for the original Apple AirPort Base Station ("Graphite"), the Lucent RG-1000 base station and the Apple Airport Extreme base station

## NAME

airport-modem - Modem monitoring and hangup utility for the original Apple AirPort Base Station ("Graphite"), the Lucent RG-1000 base station and the Apple Airport Extreme base station

## SYNOPSIS

**airport-modem**

## DESCRIPTION

**airport-modem** allows you to monitor the state of the internal modem of your base station and to start/stop the modem connection.

On the AirPort Extreme base station, the modem utility can also display the approximate duration of the modem connection.

## OPTIONS

**airport-modem** accepts no command-line options. **airport-modem** is a wrapper script around the *AirportBaseStationHangup.jar* jar file located in */usr/share/java/airport-utils*.

You can set the **JAVACMD** environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the **DEBUG** environment variable to 1 to get the debug output from the wrapper script.

## ENVIRONMENT VARIABLES

- **DEBUG**

  Set this variable to 1 to get the debug output from the wrapper script.

- **JAVACMD**

  The full path to the Java Virtual Machine to use. By default, the wrapper uses **JAVACMD**; if it is not set, it looks for **JAVA\_BINDIR**/java, then for **JAVA\_HOME**/bin/java before looking for a java executable in the **PATH**. In the latter case, the JVM used can be configured using the Debian alternatives system (see [**update-alternatives**(8)](/update-alternatives/8.md)).

- **JAVA\_HOME**

  The full path where your JDK/JRE is installed.

- **JAVA\_BINDIR**

  The full path to the directory where the java executable is located.

- **JAVA\_ARGS**

  Extra command-line arguments to be passed to the Java Virtual Machine.
