Figure 8-4: Response format
●
Header consisting of:
–
Character #
– Single digit ( 'n') which tells the number of following digits that is taken as the
size of the content.
– Number consisting of as many digits as 'n' specified ( 'LLLLL'). This number
gives the size of the content
●
Content ('user data content'), see also Figure 8-5 . As many bytes as 'LLLLL' speci-
fied.
●
Single linefeed character (symbolically shown as <LF>, Response format )
Example
The arbitrary block response data for a user data that contains 45182 bytes is:
#545182xxxxxx.......xxxxxx <LF>
The arbitrary block response data for a user data content
'THIS IS A TEST'
is:
#214THIS IS A TEST<LF>
Explanation:
'THIS IS A TEST'
has 14 bytes, and '14' has 2 digits, hence the
#214

data content. As indicated above, the user data content can have 1 or more sections
with trace measurement results, depending on the selection of auxiliary measurands.
Each section is composed of:
