3.2 Conventions Used for Examples
There are a number of command channel examples included here, and the following are the conventions used in the examples:
• All examples use <CR><LF> for the end-of-frame delimiter, and this delimiter is always denoted in hex (\x0D\x0A) since that is what
is displayed in the iVu logs and, for example, the Port Status screen.
• All commands are in bold text.
• For each example, a command request to the iVu sensor is prefaced with a >>, and a command response frame from the iVu sensor
is prefaced by a << as shown below. These are only used to make the documentation clearer.
>> get info companyname \x0D\x0A
<< OK\x0D\x0A
<< "Banner Engineering Corp."\x0D\x0A
