Defining Strings for Serial Ports and Viewports
83
The strings you create will consist of one or more elements; these elements
define the corresponding characters, data, and/or graphics (viewports only)
which will be present in the transmitted (displayed) messages. The different
elements you can use to create strings are listed below:
Literal text
Data codes
Special characters:
Newline character (N)
Character code indicator (/)
Index character (#)
Formula Indicator (%)
Field Formatting codes
The following elements are valid for
viewport strings only:
Conditional color codes Plot line codes
Draw line codes Change color codes
Literal Text
Place quotation marks ( ” ” ) around characters that you want transmitted (or
displayed) literally.
For example, you can use a literal text field to identify the type of data to
follow. You can signify specific events, such as PART REJECTED, by
defining the Event for that string so the string is transmitted (or displayed)
only if the part is rejected (see Defining the Event in this chapter).
