The Enhanced Monitor also provides several short cuts, primarily for
terminal use:
Backspace
In TERMinal mode, a backspace means "back-up." It
becomes a space in RAW mode.
Ctrl-R
In TERMinal mode, this provides a "recall last
command string" feature. It is ignored in RAW mode
Ctrl-T
In either TERMinal or RAW mode, Ctrl-T performs a
SYSTem:COMMunication:PRESet:TERMinal
command. This puts the Enhanced Monitor into its
terminal mode at whatever baud rate presently set.
Ctrl-C
In either TERMinal or RAW mode, Ctrl-C performs the
equivalent of a Device Clear. It can interrupt a
command that is taking too long to execute and makes
it possible to reset the Enhanced Monitor (*RST).
Be sure to turn off the Terminal applet's use of the control keys for Windows
use if you want to use these short cuts.
The RS-232 port can be used to program the Enhanced Monitor. Be careful
when programming this way though. Remember that you have to turn off
terminal features like echo and immediate error. Do not try to use both the
VXI programming interface and the RS-232 port at the same time. They
both access the same error queue and status registers.
You should avoid changing RS-232 port parameters through the RS-232
port. It will work but you must be careful otherwise you may lose
communications. Intersperse your commands with queries. This will help
you stay synchronized with the port. If you reattach a terminal after using a
computer and see no character echo, Ctrl-T should return the port to terminal
mode.
