Format: DSPAN,{<DEVICE I.D.>}{TERMINATOR}
Device response: <ACK> if the unit under test is able to perform the command, <NAK> if not
DZERO
Function: Commands the unit under test to enter the zero mode and stay there.
Format: DZERO,{<DEVICE I.D.>}{TERMINATOR}
Device response: <ACK> if the unit under test is able to perform the command, <NAK> if not
ABORT
Function: Commands the addressed device to abort the current mode and return to
the measure mode.
