*STB?
Syntax
*STB?
Description
Query the condition register of the Status Byte Register set.
Explanation  This command only reads the register, but does not clear it.
 The definition of each bit in the Status Byte Register is as shown in the table below.
Wherein, bit0 is not used and is always regarded as 0. Therefore, the range of
<enable_val> are the decimal numbers corresponding to the binary numbers
ranging from 00000000 (0 in decimal) to 11111111 (255 in decimal) and of which
bit0 is 0.
