Sampler Responses
The 6712 Sampler’s response string is the same for each of the
three commands. A sample response string is shown below:

5,BTL,2,SVO,100,SOR,0,CS,xxxx<CR>
Note that the sampler’s response is a series of alphabetical and
numerical pairs. The alphabetical characters are headings that
describe the following numerical value or code. A complete
description of each pair is listed below.
MO,6712, is the model number of the sampler.
ID,2424741493, is the sampler’s unique identification number.
TI,35523.50000, is the sampler’s current time.
