RS-232 / Serial port command examples
The following examples demonstrate how to use some of the RS-232 commands supported by the system.
The list of supported SET and GET parameters are found in
Configuration keys for third party APIs .
Each command sent to the Networked VGA Grid via RS 232 must be terminated with a line feed
(LF) character (ASCII code 10). Your software may need to be configured to add the line feed to
each command.
For values with spaces, enclose the value in quotation marks. For empty values, use empty quotation marks
with nothing between.
You must always follow a "SET" command in RS-232 with the "SAVECFG" command. Otherwise the
new configuration setting(s) will not take effect. See "SET" examples below.
