SHOW Function Attributes and Attribute States
The Show command provides an ASCII response formatted for printing. The driver parses these messages and converts the
data to numbers which can be sent to Client devices using another protocol.
The driver performs the following tasks in analyzing the response.
On a line by line basis from the left, it searches for an attribute against a table of attribute strings. If an attribute string is
found, processing continues. Otherwise the line is discarded.
The attribute number is used to determine the array location where the attribute state/value will be stored.
The attribute also determines the state/value extraction method.
Method 1: The driver compares the remainder of the line against a table of attribute states. The value of the
attribute state is stored in the array location determined by the attribute,
Method 2: The driver looks for (up to three) analog values separated by forward slashes.
Method 3: The driver looks for analog values preceded by an equal sign.
The driver stores in the first array location the number of response lines which resulted in attribute data being stored.
This information can be used for troubleshooting.
