COMMANDS DESCRIPTION
Values sent or received are in decimal. Depending on the command letter, the value can be used as a linear control (ex :
255W to set the horizontal size to the maximum) or as a set of bits (ex : P command with multiple controls). In this case,
the value must be converted in binary base to understand every bit action.
EXAMPLE Host receives message CSTA3 (P command)
Decimal value 3 = Binary value 011
3 = (4 x 0) + (2 x 1) + (1 x 1)
bit 0 = 1 means Sync. detected.
bit 1 = 1 means Comp. Sync. detected.
bit 2 = 0 means non interlaced format detected.
