Agilent Technologies 34401A - Chapter 4 RS-232 Interface Commands; RS-232 Interface Commands

RS-232 Interface Commands
Use the front-panel I/O MENU to select the baud rate, parity, and
number of data bits (see pages 163 and 164 for more information).
SYSTem:LOCal
Place the multimeter in the local mode for
RS-232 operation. All keys on
the front panel are fully functional.
SYSTem:REMote
Place the multimeter in the remote mode for
RS-232 operation.
All keys on the front panel, except the
LOCAL key, are disabled.
It is very important that you send the SYSTem:REMote command
to place the multimeter in the remote mode. Sending or receiving data
over the RS-232 interface when not configured for remote operation can
cause unpredictable results.
SYSTem:RWLock
Place the multimeter in the remote mode for
RS-232 operation.
This command is the same as the SYSTem:REMote command except
that all keys on the front panel are disabled, including the
LOCAL key.
Ctrl-C
Clear the operation in progress over the
RS-232 interface and discard
any pending output data. This is equivalent to the IEEE-488 device clear
action over the GPIB interface.
