command instructs the generator to use the new settings. The ALLU command updates
the hardware to the new settings and redraws the test image.
Example
FSPG 1 // Enable Frame Sync
FSPP 1 // Set for positive going pulse
FSPW 20 // Make the pulse 20 pixels wide
FSPG 300 // Pulse to occur 300 lines after
// the last line of active video
FMTU // Update hardware to new settings
