In addition to the above constants, requestEventRegister can be set to the decimal equivalent of
the bits set. When more than one bit of the register is set, requestEventRegister contains the
sum of their decimal weights. For example, if 129 is returned, bits B0 and B7 are set (1 + 128).

Description
Set summary bit indicates that an enabled event in
the Measurement Event Register has occurred.
Bit B0 decimal value: 1
This bit is only available on Models
2601B/2602B/2611B/2612B/2635B/2636B. Set
summary bit indicates that an enabled event in the
System Summary Register has occurred.
Bit B1 decimal value: 2
Set summary bit indicates that an error or status
message is present in the error queue.
Bit B2 decimal value: 4
Set summary bit indicates that an enabled event in
the Questionable Status Register has occurred.
Bit B3 decimal value: 8
Set summary bit indicates that a response message
is present in the output queue.
Bit B4 decimal value: 16
Set summary bit indicates that an enabled event in
the Standard Event Status Register has occurred.
Bit B5 decimal value: 32
Not applicable
Set summary bit indicates that an enabled event in
the Operation Status Register has occurred.
Bit B7 decimal value: 128

Reads the status request event register.
Sample output:
1.29000e+02
Converting this output (129) to its binary
equivalent yields 1000 0001.
Therefore, this output indicates that the set bits of
the status request event register are presently B0
(MSB) and B7 (OSB).
