20: Abort any bus activity and return the HP-IB interfaces to
their reset states.
30: Place the source into LOCAL to cancel'any Local Lockouts
that may have been setup. 40: Reset the source's parser and clear
any pending output from the source. Prepare the source to receive
new commands.
50: Place the source into REMOTE.
60: Clear the display of the computer.

When the synthesizer is in REMOTE mode, all the front panel
keys are disabled except the LOCAL key. But, when the LOCAL
LOCKOUT command is set on the bus, even the LOCAL key is
disabled. The LOCAL command, executed from the controller, is
then the only way to return all (or selected) instruments to front
panel control.
