*SRE <mask>
Service Request Enable. When a service request event occurs, it sets
a corresponding bit in the Status Byte Register (this happens whether or not the event
has been enabled (unmasked) by *SRE). The *SRE command allows one to identify
which of these events will assert an GPIB service request (SRQ). When an event is
enabled by *SRE and that event occurs, it sets a bit in the Status Byte Register and
issues an SRQ to the computer (sets the GPIB SRQ line true). An event is enabled
by specifying its decimal weight for <mask>. To enable more than one event, specify
the sum of the decimal weights. Refer to "The Status Byte Register" for a table
showing the contents of the Status Byte Register. The data type for <mask> is int16.
