Note: The config command does not verify whether the nodes edited/added by the user are valid. This
means that any node may be added to the tree. If a user runs the following command:
# /bin/config -s config.fruit.apple=sweet
The configurator will not complain, but this command is useless. When the configurators are run
(to turn the config.xml file into live config) they will simply ignore this <fruit> node. Administrators
must make sure of the spelling when typing config commands. Incorrect spelling for a node will
not be flagged.
Most configurations made to the XML file will be immediately active. To make sure that all configuration
changes are active, especially when editing user passwords, run all the configurators:
# /bin/config -a
For information on backing up and restoring the configuration file, refer to Chapter 15, Advanced
Configuration.
14.2 Serial Port configuration
The first set of configurations you need to make to any serial port are the RS-232 common settings. For
example, setup serial port 5 to use the following properties:
Baud Rate 9600
Parity None
Data Bits 8
Stop Bits 1
label Myport
log level 0
protocol RS232
flow control None
To do this, use the following commands:
# config -s config.ports.port5.speed=9600
# config -s config.ports.port5.parity=None
# config -s config.ports.port5.charsize=8
# config -s config.ports.port5.stop=1
# config -s config.ports.port5.label=myport
# config -s config.ports.port5.loglevel=0
# config -s config.ports.port5.protocol=RS232
# config -s config.ports.port5.flowcontrol=None
The following command will synchronize the live system with the new configuration:
# config -r serialconfig
Note: Supported serial port baud-rates are ‘50’, ‘75’, ‘110’, ‘134’, ‘150’, ‘200’, ‘300’, ‘600’,
‘1200’, ‘1800’, ‘2400’, ‘4800’, ‘9600’, '19200', '38400', '57600', '115200', and '230400'.
Supported parity values are 'None', 'Odd', 'Even', 'Mark' and 'Space'.
Supported data-bits values are '8', '7', '6' and '5'.
Supported stop-bits values are '1', '1.5' and '2'.
Supported flow-control values are 'Hardware', 'Software' and 'None'.
Additionally, before any port can function properly, you need to set the port mode. Set any port to run
in one of the five possible modes (refer Chapter 4 for details): [Console server mode|Device mode|SDT
mode|Terminal server mode|Serial bridge mode]. All these modes are mutually exclusive.
