SOH-'0'-'A'-'0'-'A'-'0'-'4'-STX-'0'-'7'-ETX-CHK- CR
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 Rese rved (Do n't care )
Bi t 1 1:P osit ive Hori zont al s ync pola rity
0: Nega tive Hor izon tal sync polarity.
Bit 0 1:P osit ive Vert ical syn c po lari ty.
0: Nega tive Ver tica l sy nc 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.
