255: CLIP^TRACE^BLOCK
For an unnumbered frame, the abbreviation for the SDLC command or
response (for example, SNRM or UA) appears following the letter U.
For all three types of frames, the presence of the characters -P or -F indicates
that the poll/final (P/F) bit is set; the absence of these characters indicates that
the poll/final bit is not set.
In the subrecord above, the receive-ready count is now 1, indicating that the
remote entity has received the previous information frame.
The control field is described fully in the IBM Synchronous Data Link Control
Concepts.
Frame bytes: n
gives the total number of bytes in the frame. This is the total length of the
frame, even if a small RECSIZE value in the TRACE command caused the
data in the trace record to be truncated.
C831 ...
is the contents of the frame, starting with the address field.
The next subrecord is for another CLIP level-2 state-machine event, as previously
described.
17:13:56.78 Host Rsp: 4100 0001 0000 0001 01
is a subrecord indicating a response from the host. This response is passed to the
CLB and eventually returned to the line handler. Here it is a text-sent message, as
noted previously.
The last three subrecords are for additional CLIP level-1 and level-2 state-machine
events, as previously described.
