5.10.13 *SRE? service request enable query
To read the contents of the Service Request Enable Register.
*SRE?
The *SRE? command is used to acquire the value (in decimal) of the Service Request Enable
Register. The binary equivalent of the decimal value determines which bits in the register are
set. When the *SRE? query command is sent, the decimal value is placed in the Output Queue.
When the Model 7001 is addressed to talk, the value is sent from the Output Queue to the com-
puter.
For example, for an acquired decimal value of 17, the binary equivalent is 0001 0001. This bi-
nary value indicates that Bits 4 and 0 of the Service Request Enable Register are set (see previ-
ous paragraph).
10 OUTPUT 707; “*SRE?” ! Request contents of SRER
20 ENTER 707; A$ ! Address 7001 to talk
30 PRINT A$ ! Display value register
