2.2.2 IEEE 488 Bus Output Terminator Selection

The terminating characters sent on output by the Digital488 are

determined by SW1-6 through SW1-8. The terminator switches are read
only at power on, but can be changed by the controller through the
Terminator command. If power is cycled after receipt of the Terminator
command, then the unit will once again default to the switch settings. The
factory default settings are Carriage Return - Line Feed with EOI asserted.

The Digital488 ignores all terminators received from the bus

controller. Only the Execute command (X) is used to signal the Digital488
that a command string has been completed.
