<null
= 0...15
radius>
Returns: The selected null radius (in the
same format as the command).
For example, The packet "nH\r" sets the null
radius to 8. At this setting, movements of the
cap (both translational and rotational) from its
center position that correspond to about 2% or
less of the cap's maximal displacement range
will only generate values of zero.
Null Radius ? Command
Function: Interrogates the current null
radius setup.
Command: nQ\r
Returns: n<nibble>\r

section, Null Radius Setup Command.
Beep Command
Function: Activates (or deactivates) the
internal beeper of the Magellan/
SPACE MOUSE for the specified
amount of time.
Command: b<nibble>\r
<nibble> <B7...4> < B3 > <B2><B1><B0>
<on/off>
= 1 Magellan/SPACE MOUSE beeps for
the specified duration.
= 0 The beeper is silent for the
specified duration.

= 5 1000 milliseconds
= 4 500 milliseconds
= 3 250 milliseconds
= 2 125 milliseconds
= 1 64 milliseconds
= 0 32 milliseconds
Returns: b\r
For example, the command "b<\r" activates
the beeper for half a second.
Flash Command
Function: Activates the internal flasher of
the Magellan/SPACE MOUSE for
the specified amount of time.
The smallest movement of the
cap necessary to generate a
nonzero value is defined,
where zero requires the
smallest movement and 15
requires the largest.
