Consideration
The maximum amount of user data you can send with this primitive depends on the
layer of your connection, whether you are using session version 1 or session version 2,
and (for presentation and ACSE connections) whether your connection is in normal
mode or X.410-1984 mode. The maximum length of the user-data parameter is as
follows:
Session version 1 Session version 2
Session connection 0 bytes 10240 bytes
Presentation connection (normal mode) 0 bytes < 10240 bytes
ACSE connection (normal mode) 0 bytes < 10240 bytes
For a normal-mode presentation or ACSE connection using session version 2, you can
send as much data as will fit in a 10240-byte PPDU; the maximum length depends on
the encoding.
For a presentation or ACSE connection in X.410-1984 mode, the maximum amount of
data is the same as that for a session connection.
