Status of this document
-----------------------
This document is a Fidonet Reference Library document (FRL).
This document preserves FSP-1021.001, which was not promoted to
Fidonet Technical Standard status for the reasons stated below.
This document is released to the public domain, and may be used,
copied or modified for any purpose whatever.
Adjudication
------------
FSP-1021 was not promoted to Fidonet Technical Standard status as
it describes an obsolete and accidental feature (ie. bug) in
certain implementations.
1. Definitions
--------------
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL"
in this document are to be interpreted as described in [FTA-1006].
2. Binkp Multiple Batch Mode
----------------------------
The session is in MB mode if both sides set "MB" flag in any of
M_NUL "OPT" packets exchanged before sending of M_OK/M_PWD packets.
This extension may only be used in protocol version binkp/1.0,
not in any later version. Since binkp/1.1 there is another method
to have multiple batches, this method is not compatible with the
MB protocol extension.
In MB mode both sides restart session from RxDone and TxDone into
InitTransfer state if there were any command frames sent or
received by any side between starting at InitTransfer and
exchanging of M_EOB by the sides (RxDone state). Otherwise, the
session terminates as usual. The new batch may not start before
both sides have send the M_EOB frame and have received the M_EOB
frame, in other words the mailer must be in the state RxDone and
TxDone.
Multiple batches mode is intended to handle WaZOO [FTS-0006] file
requests. If there were any WaZOO request files transferred in a
batch, sides MAY process them and send resulting files in the next
batch. Mailers MAY also generate list of files to send in
additional batches by other techniques -- including rescanning of
their spools or processing of other magic files transferred before
in the same session.
2.1 Example of frame exchange in a simple binkp MB session
----------------------------------------------------------
Originating side (1:1/1.1@fidonet) has file1 for answering side
(2:2/2.2@fidonet) and answering side has file2 for originating side

2.2 Example of frame exchange with multiple batches
---------------------------------------------------
Originating side (1:1/1.1@fidonet) has file request and file1 for
answering side (2:2/2.2@fidonet) and answering side has file2 for
originating side. File "freq" is a WaZoo file request. File "resp"
is the file that is send in response to the file request.
