Description
Returns the current status of the generator's signal generating hardware as a single
decimal number. The number corresponds to the status of the lighted key on the generator
in normal operation. The easiest way to interpret the number is to first convert it to an
8-digit binary number. A 1 in a given position, from MSB to LSB, corresponds to the
following hardware settings:
Master output control gated ON
(MSB)
Digital Separate (HS&VS) Sync selected
Digital Composite Sync selected
Analog Composite Sync selected
Blue video enabled
Green video enabled
Red video enabled
Alternate image version selected
(LSB)

// HS & VS is selected, the red, green and blue video channels are
// enabled and the primary version of an image is selected.
206 // Binary equivalent = 11001110
