The following command enables bit 4 (decimal value = 16) in the enable
register. If an Execution Error occurs, this condition will be reported to
the Status Byte Register (bit 5 will be set to high).

The decimal value specified corresponds to the binary- weighted sum of
the bits you wish to enable in the register. For example, to enable bit 2
(decimal value = 4), bit 3 (decimal value = 8), and bit 7 (decimal value
= 128), the corresponding decimal value would be 140 (4 + 8 + 128).

"0" is returned
The instrument tried to read the output buffer but it was
empty. Or, a new command line was received before a
previous query has been read. Or, both the input and
output buffers are full
"0" is returned
An execution error occurred
A command syntax error occurred
"0" is returned
Power has been turned off and on since the last time
