7.1.2 MODE READER
MODE READER SHOULD be sent by any client that intends to use any
command other than IHAVE, HEAD, STAT, LIST, LIST EXTENSIONS, or
commands advertised by the server as available via LIST EXTENSIONS.
Servers MAY require that this command be issued before any other
commands are sent and MAY reject any other commands until after a
MODE READER command has been sent.
The server MUST present a response using the same codes as the
initial greeting (as described in section 7.1) to indicate its
ability to provide reading service to the client.
Clients SHOULD wait for a response to MODE READER after sending this
command and SHOULD NOT send any additional commands until that
response has been received from the server.
Once MODE READER is sent, IHAVE (and any extensions intended for
peer-to-peer article transfer) MAY no longer be permitted, even if
it were permitted before the MODE READER command.
Servers are encouraged to not require this command even though
clients SHOULD send it when appropriate. It is present to support
some news architectures which switch between modes based on whether
a given connection is a peer-to-peer connection with another server
or a news reading client. It is preferrable instead to accept
peer-to-peer connections on a different port and to assume that
all connections to the standard NNTP port are from news reading
clients.
[Responses and Examples unchanged from the current draft.]
