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 -h or --help argument 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.
