Command Parser Rules

•
A command consists of a mnemonic (for example, CLOSE) and, if required, a data
parameter. The mnemonic and the data parameter must be separated by at least one
space.
•
Parameters can be entered in various formats; for example, 10, 10.0, and 1.0e1 are all
recognized as the same value.
•
Commands can be sent in uppercase or lowercase characters.
