 If you want to review the existing control points in your configuration, go to the ‘Control
Points’ table under the ‘Views’ pane.
Serial control points are expressed as a text string beginning with S and containing several
fields, separated by commas. Simple Ethernet control points are expressed as a text string
beginning with E, followed by a comma, followed by an IP address. This is a sampling:
These are the parts of the serial encoding, from left to right:
• The COM port number.
• The Baud rate.
• The communication parameters.
This is a 3-character term. The first character is the number of parity bits. “N” means no parity
bit. The second character is the number of data bits. Normally this is 8. The third character is
the number of stop bits. Normally this is 1.
The default for most serial ports is “N81.”
For simple Ethernet encoding, only an IP address is required. Some routers require additional
fields (“control point modifiers”) for which both syntax and meaning depend on the actual hard-
ware supported through the control point.
Params
The control point for certain kinds of interfaces can accept parameters. You can express the
parameters for an interface in this field if you know the parameter or parameters.
