Device Talking Syntax
The talking syntax of IEEE 488.2 is designed to be more precise than the
listening syntax. This allows the programmer to write routines which can
easily interpret and use the data the instrument is sending. One of the
implications of thii is the absence of
-z
white space > in the talking
formats. The instrument will not pad messages which are being sent to the
controller with spaces.
<
response message
> . This element serves as a complete response from
the instrument. It is the result of the instrument executing and buffering
the results from a complete c program message
>
. The complete
c
response message > should be read before sending another c program
message

to the instrument.
