Table 6-1 lists the RS-232 command set. The “Parameter (min/max)” column shows the
valid parameter ranges, or “NA” for commands that take no parameters.
When you enter a valid command, the DHD Controller executes it and acknowledges it
with a plus sign on the command line (+ >). When you enter an invalid command – one
that is misspelled or followed by values outside the valid range for that command – the
DHD Controller ignores it and returns a minus sign (- >).
