1 ESC F command
2 data block
Explanation:
When this command is received, the scanner sends a data block
indicating the current status of the scanner. The current status can be
determined by reading the flags of the status byte. See Chapter 2 for
details on the status byte.
The data block contains only an information block, and is not
followed by data. Because of this, the value of the byte counter is
always null.
