Commands above which are appended with '*' come from BusyBox (the Swiss Army Knife of embedded Linux) http://www.busybox.net/downloads/BusyBox.html. Others are generic Linux commands and most commands the -hor --helpargument to provide a terse runtime description of their behavior. More details on the generic Linux commands can found online at http://en.tldp.org/HOWTO/HOWTO- INDEX/howtos.html and http://www.faqs.org/docs/Linux-HOWTO/Remote-Serial-Console-HOWTO.html

An updated list of the commands may found using ls command to view all the commands actually available in the /bin directory in your console server.

There were a number of Black Box tools listed above that make it simple to configure the console server and make sure the changes are stored in the console server's flash memory, etc. These commands are covered in the previous chapters and include:

•config which allows manipulation and querying of the system configuration from the command line. With config a new configuration can be activated by running the relevant configurator, which performs the action necessary to make the configuration changes live.

•portmanager which provides a buffered interface to each serial port. It is supported by the pmchat and pmshell commands which ensure all serial port access is directed via the portmanager.

•pmpower is a configurable tool for manipulating remote power devices that are serially or network connected to the console server.

•SDT Connector is a java client applet that provides point-and-click SSH tunneled connections to the console server and Managed Devices.
