                        LETTER TO TIP USERS -- 2


     This is the second letter to TIP users.  The first was RFC #365.
There will be more letters to TIP users as they seem to us to be a
good way to keep you informed about what's going on.  We suggest you
keep these letters with your TIP User's Guide (TUG) as we will use the
letters to provide documentation of TIP system changes which are made
before we can get TUG revisions printed and distributed. (It is almost
inevitable that the TUG revisions follow actual system changes.
Further- more, these letters will allow us more discussion of new
commands than in TUG.)

     Some of the changes we will be making to the TIP have been
suggested by TIP users. We won't bother with acknowledg- ments.

     The @PROTOCOL TO LOGIN and @PROTOCOL TO CLOSE BOTH commands will
be removed very soon. We presume no one uses these commands any more
since they have been replaced by @LOGIN and @CLOSE.

     As we warned in TIP Letter 1, the @LOGIN command will be given a
parameter soon, the Host number up to now given with the @HOST
command.  At the same time, @HOST will be changed so it does a
simultaneous @RECEIVE FROM HOST and @SEND TO HOST.  Presently, @HOST
is the same as @SEND TO HOST.

     Several changes will be made to the @TRANSMIT commands very soon.
First @TRANSMIT ON NO CHARACTERS and @TRANSMIT ON EVERY CHARACTER will
be removed. Their functions will be covered by the other @TRANSMIT
commands. @TRANSMIT NOW will continue to function as at present; it
will cause the one message presently being accumulated to be sent as
soon as possible.  @TRANSMIT ON LINEFEED and @TRANSMIT ON MESSAGE-END
will continue to cause the message being accumulated to be sent on
linefeed and CONTROL-S. However, they will additionally cause the
message being accumulated to be sent when the character buffer is
almost full. Thus, it will no longer be necessary to give a @TRANSMIT
EVERY  with @TRANSMIT ON LINEFEED and @TRANSMIT ON
MESSAGE-END.  @TRANSMIT EVERY # will continue to cause the message
being accumulated to be sent as near as possible to every #th
character.  However, values of # which are bigger than the size of the
