read up to the next non-numeric character).
8. Read the graph results (if any) using the S?n command where n is the graph handle.
Repeat for each graph handle that was found. Note that the S?n command returns three
lines of text, representing the start and finish frequencies and the number of samples.
This is followed by 2 bytes per sample for every sample (this is always 256 in current
software). This binary data should be held in a buffer, as it is, without processing.
9. Send a KB1 command to return the LA100 to manual mode.
Read Segment List: 2R?n (retained for backward compatibility - 2SR?

R? read results
The segment list for register n is returned, or for both registers if n is omitted. The
segment list is simply the list of segments received and each list is terminated with a CR
character. Register 1 normally holds the results for the left channel, while register 2 holds
the results for the right channel (but see single register operation in sections 3.12 and
9.14). After running the default sequence 1 for example, the R? command would return
two lines: +TRCINZ and TRCIN. If a register contains no segments then a blank line is
returned.
Read Results: 2R?r,xxx...(retained for backward compatibility - 2SR?

Read results Reading results values remotely
This command reads the results for the specified segments (xxx...) in register r. The
segment letters should all be in the segment list (as read using R? without a segment list,
see above) for the register(s) being read. All results are returned in ASCII decimal
(typically with 2 decimal places) and every value is terminated with a CR character (ie
one result value per line). The register number r should be 1 or 2 to read the results from
a particular register and this usually corresponds to the L and R channels respectively (but
see sections 3.12 and 9.15). Alternatively r can be omitted to read pairs of results for the
two registers (register 1 value, then register 2 value, with every value terminated with a
CR). This latter form should only be used where the segment appears in both segment
lists (ie it is not generally suitable for reading phase results which are usually only in one
register).
Every segment has a fixed number of results value, as shown in table 3.2, and the results
values for each segment are returned in the same order as they are printed (not the order
in which the measurements are performed). The source ID text can also be read by
putting a + character in the list of segments − it will be returned as a single line of text (up
to 21 characters long) terminated with a CR character.
Some examples should clarify this:
R?1,T Read Test Level for L channel (register 1)
R?2,D Read distortion results for R channel (100Hz, 1kHz and 6.3kHz)
R?,D Read 6 distortion measurements:
100Hz L, 100Hz R, 1kHz L, 1kHz R, 6.3kHz L, 6.3kHz R
