program. The second method has the advantage of allowing the commands to be
saved, viewed, edited and resent. The text editor used must save the configuration
files as 8 bit ASCII data.
Space or tab characters before a command or trailing a command are ignored, as
are spaces or tabs following a comma that separates parameters within a
command. Any characters on a line following a tick (') character are treated as
comments. A comment may begin after a delimiter, or may follow a command with
or without spaces or tabs between the command and the comment.
ASCII string parameters are delimited with quotation marks. If a quotation mark or
backslash character is required within a string (for example to display as part of a
text overlay), then it must be preceded by a backslash character.
Valid and invalid serial commands are acknowledged with a ‘+’ and ‘-’ response
respectively. Carriage return, line feed, or semicolon characters without a
pr
eceding command are acknowledged with a ‘*’.
The command codes are extensible, additional commands and functionality can
be added as required. Contact Microtronix sales or technical support with your
requirements.
