DESE
Sets or returns the bits in the Device Event Status Enable Register (DESER). The
DESER is the mask that determines whether events are reported t o the Standard
Event Status
Register (SESR), and entered into the E vent Queue. For a detailed
discussion of the use of these registers, see Registers.

Arguments
<NR1> sets the binary bits of the DESER according to this value, which ranges
from 1 through 255. For example, DESE 209 sets the DESER to the binary value
11010001 (that is, the most significant bit in the register is set to 1, the next most
significant bit to 1, the next bit to 0, etc.).
The power-on default for DESER is all bits set if *PSC is 1. If *PSC is 0, the
DESER maintains the previous power cycle value through the c urrent power cycle.
NOTE. Setting the DESER and ESER to the same value allows only those codes
to be entered into the Event Queue and summarized on the ESB bit (bit 5) of the
Status Byte Register. Use the *ESE commandtosettheESER.
Examples
DESE 209 sets the DESER to binary 11010001, which enables the PON, URQ,
EXE and OPC bits.
DESE? might return :DESE 186, showing that the DESER contains the binary
value 10111010.
