Returned Query Format
<NR1>
The query command reads the condition register and returns a decimal
value which corresponds to the binary-weighted sum of all the bits set in
the register (refer to the table under Remarks). For example, if bit 1
(decimal value = 2) and bit 4 (decimal value = 16) are set (and the
corresponding bits are enabled), this command will return "+18".

The following command reads the condition register (bits 3 and 4 are set).
