commands
To get a pulse, frame sync must first be enabled with the FSPG command. The FMTU
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
