5.2.4 GPIB bus function
TX7410 will respond to the following bus commands.

ABORT I/O (IFC)
ABORT I/O (IFC control line TRUE) halts all bus activity and deselects TX7410 .

DEVICE CLEAR (SDC or DCL)
This command can be used with an address to clear a particular device (SDC : selected
device clear) or used without an address (DCL : clears all devices). The Input buffer is
cleared, output data buffer is cleared and bit 4 (MAV bit) of the status byte is set to “0”,
when TX7510 receives this command.

LOCAL (GTL)
LOCAL returns control of a listening device to front panel control.

REMOTE (RMT)
REMOTE sets TX7410 to the remote mode. When this command is sent, front panel with
the exception of LOCAL softkey will be disabled.

TRIGGER (GET)
It enables TX7410 to the TRIGGER bus command. This command may be sent to a
selected device or to all devices addressed as listeners on the GPIB bus. TX7410 must first
be addressed as a listener, second the trigger mode is set to the BUS trigger mode before
the trigger message is sent. This command is equal to the SCPI command TRIG+FETCh?
or the common command *TRG.
