SOH-'0'-'A'-'0'-'A'-'0'-'4'-STX-'0'-'D'-ETX-CHK- CR
The monitor replies the packet for confirmation as follows;
SOH-'0'-'0'-'A'-'B'-'0'-'6'-STX-'0'-'0'-'0'-'D'-ETX-CHK- CR

The controller requests the monitor to report the displayed image timing.
Send "07"(30h, 37h) as Get Timing Report command.
Complete "Get Timing Report" command packet as follows;
(The destination “A” (monitor ID of 1) is only an example. It should be changed according
to the target monitor ID)

The monitor replies status as the following format;
SS: Timing status byte
Bit 7 = 1: Sync Frequency is out of range.
Bit 6 = 1: Unstable count
Bit 5-2 Reserved (Don't care)
Bit 1
1:Positive Horizontal sync polarity.
0:Negative Horizontal sync polarity.
Bit 0
1:Positive Vertical sync polarity.
0:Negative Vertical sync polarity.
H Freq: Horizontal Frequency in unit 0.01kHz
V Freq: Vertical Frequency in unit 0.01Hz
Ex.) When H Freq is '1''2''A''9' (31h, 32h, 41h, 39h), it means 47.77kHz.
