EQ for each physical or virtual channel. The <index> arguments are integer arguments used to address
parameters with a dimensionality of one or higher. The dimensionality of a command is given in the specific
requirements for that command.
<arg>
The meaning of the argument is specific to each parameter. The syntax of an argument is determined by its
type. Some uses of commands do not require an argument (for example, get, to get the value of a parameter
does not need an argument).
Parameter Modes
Each parameter command enforces one of the following modes for its parameter.
Parameter Modes
Parameter Mode Description
read-write the parameter may be both queried and set
read-only the parameter may be queried, but not set
write-only the parameter may be set, but not queried
Thus, read-write commands support the get and set actions and support the inc, dec, or tog actions
depending on the parameter type. Read-only commands support the get action, but do not support the set,
inc, dec, or tog actions. Write-only commands support the set action, but do not support the get, inc, dec,
or tog actions.
Parameter Types
All commands fall into one of the following types.
Void
Commands to adjust void parameters that take no arguments. Void parameter commands support the set
action. Void parameter commands do not support the get, inc, dec, or tog actions. Void parameter
commands must always be write-only. An example of a void command is the sys_reboot command, which
performs a software reset when set.
Boolean
A Boolean parameter command's argument is an integer argument that must be either 0 or 1. Boolean
parameter commands support the get, set, and tog actions according to the command's read-write mode.
The tog action causes the parameter to change state (for example, 0 changes to 1, and 1 changes to 0).
Boolean parameter commands do not support the inc and dec actions.
Integer
Integer parameter commands control integer-valued parameters with values in the range of -2,147,483,648
(-2^31) to 2,147,483,647 (2^31 - 1), inclusive. The specific command will most likely impose minimum and
maximum limits more restrictive than this range. The argument to an integer parameter command is an
integer argument.
Integer parameter commands support the get, set, inc, and dec actions according to the command's
read-write mode. Integer parameter commands do not support the tog action. Integer parameter commands
