The Status Byte
The analyzer has a status-reporting mechanism that reports information
about specific analyzer functions and events. The status byte (consisting
of summary bits) is the top-level register. Each bit reflects the condition
of another register or queue. If a summary bit is set (equals l), the
corresponding register or queue should be read to obtain the status
information and clear the condition. Reading the status byte does not
affect the state of the summary bits. The summary bits always reflect
the condition of the summarized queue or register.
The status byte can be read by a serial poll or by using the command
OUTPSTAT. OUTPSTAT does not automatically put the instrument in
remote mode, thus giving the operator access to the analyzer front-panel
functions. OUTPSTAT will return an ASCII (text) integer (O-255) that can
be interpreted as the Shit status byte. Using the OUTPSTAT command
