L5 PROV—L5 I/O Completion Continuation
Another example of an L5 I/O Completion record follows. It shows the completion of a
read of part of an SPDU. It is not possible to predict from this record whether the data
will be combined into a larger buffer or sent directly to the L5 service user.

Note: If this is a read completion and if the incoming TSDU contains
part of a DT or TD SPDU, the TSDU data will be sent to the session
service user in fragments as it is read from transport. If the TSDU
contains a different type of SPDU, the whole SPDU will be read in and
assembled before being passed to the session service user. %H0001 is
also set when writing part of a larger TSDU.
