Command/response table for special function SIS commands

The syntax for setting a special function is Xn * X? # where Xn is the value or variable (such as X17 in the second example below), X? is the function number (such as

“2” = “Set input 5 video format” in the second example below), and # is the execute command. To view a function’s setting, use X? #, where X? is the function number.
