The id appears on the web page in the list of available devices types to
configure.
The outlets describe targets that the scripts can control. For example a
power control board may control several different outlets. The port-id is
the native name for identifying the outlet. This value will be passed to the
scripts in the environment variable outlet, allowing the script to address
the correct outlet.
There are four possible scripts: on, off, cycle and status
When a script is run, it’s standard input and output is redirected to the
appropriate serial port. The script receives the outlet and port in the
outlet and port environment variables respectively.
The script can be anything that can be executed within the shell.
All of the existing scripts in /etc/powerstrips.xml use the pmchat utility.
pmchat works just like the standard unix “chat” program, only it ensures
interoperation with the port manager.
The final options, speed, charsize, stop and parity define the
recommended or default settings for the attached device.
