Step SECS Message Description
1. H -> E SnFn [W] Host sends a message with a stream and
function that the Equipment recognizes, but
contains more data than expected. The W-bit
can be either 0 or 1.
2. H <- E S9F11 Equipment replies with „Data Too Long“. If the
erroneous message is a primary with the W-bit
set to 1, then in come cases the Equipment will
reply with the usual secondary response with an
appropriate error code, instead of S9F11. If the
erroneous message is a secondary, the
Equipment makes no reply at all.
