This query command is used to read the bit pattern that is actually on the
digital output port.
<name> = EOTest
BUSY
:MODE?
This command controls the operation of digital I/O line 4 to act as either
an End-of-Test or Busy signal in the 3-bit output mode. EOT is not auto-
matically controlled in 4-bit mode. See
wise, with BUSY enabled in the 4-bit mode, the unit behaves as if it
were in 3-bit mode by ignoring all attempts to drive digital I/O line 4.
