Standard Event Status Register Query

*ESR?
Queries and clears the standard event status event register. (This is a
destructive read.)
Range: Integer, 0 to 255
Identification Query
*IDN?
Returns an instrument identification information string. The string will
contain the model number, serial number and firmware revision. The
response is organized into four fields separated by commas. The field
definitions are as follows:
Manufacturer
Model
Serial number
Firmware version
For example:
Hewlett-Packard, E4401B, US00000013, A.00.00

Instrument State Query

*LRN?
Returns current instrument state data in a block of defined length. The
information is in a machine readable format only. Sending the query
returns the following format:
#PQQQSYST:SET #NMMM<state_data>
The following example is a response to *LRN? The actual sizes will vary
depending on the instrument state data size.
Example:
#42031SYST:SET #42016<state data>
The number 4 (P in the preceding query response format) means there are 4
numbers that make up the size of the data that follows. In this example,
2031 bytes will follow the number 4 (42031).
2031 and 2016 (QQQ and MMM in the preceding query response format)
represent data size in bytes.
