b. Scanning suspension command - 0x44 (‘D’ ASCII)
Momentary suspends the scanning and passes the control to the host.
Host sends:
0x02 0x01 0x44 0x03 0xBA
DS2 responds:
0x02 0x01 0x64 0x03 0x9A
The following figure is similar to the previous one with the difference that the scanning now does not
re-start automatically after receiving the command (see point 9).
c. Scanning re-start command - 0x45 (ASCII ‘E’ )
Informs DS2 to re-start the normal scanning mode and the host looses the line control.
Host sends:
0x02 0x01 0x45 0x03 0xB9
DS2 replies:
0x02 0x01 0x65 0x03 0x99
In this case the SYN codes do not have to be sent as the scanning is suspended.
The command is accepted immediately. After the exchange of the packets (see points 1 and 2),
DS2 re-starts the scanning (see point 3).
