DSP
DSP
command/query
The :SYSTEM:DSP
command writes
a
quoted string, excluding
quotes,
to
the advisory line (line 1)
of
the CRT.
The DSP
query returns the last
string written
to
the advisory
line. This
may be
a
string written with
a
DSP command or an internally generated
advisory.
The
string is actually read from the message queue. The
message queue
is
cleared when
it is
read.
Therefore
the
displayed
message can
only
be read
once over the
bus.
