correctly enumerated by the controlling computer.

NULL
In this setting the ASCII character responses that the instrument sends returns via
the USB interface are terminated in a null character
STATUS

5.3.20 Communications Monitor

When the Communications Menu is displayed, pressing the Communications
monitor key accesses the Communications monitor display, shown in figure 5-26. It
may also be accessed via the RS232 Settings and USB Status menus.
The monitor is useful when attempting to establish communications via the computer
interfaces for the first time, or if a problem is suspected.
The Input side of the display shows all of the characters that have been received from
the interface, whether valid or not. The Output side of the display shows all the
characters that have been generated by the instrument and sent to the interface.
If characters received do not match those sent by the controlling computer then this
indicates that an error has occurred either in the host computer or interface cable. If
the interface cable is known to be good, then re-check either the RS232 or USB
communications settings.
