Normally, the H1 parameter is 0, allowing the ICC1-232 to use the current H1 tuning
format, but it could be used to force a different tuning option. When the display is
set to the H1=1 mode, 1-part digital channel, the first byte is (x*256), and the last
byte is the value you add to state the channel number. In H1=2 or 3 modes, the
bytes represent the Major and Minor channel numbers.
