SIMTEL20 files are also available from mirror sites OAK.Oakland.Edu
(141.210.10.117), wuarchive.wustl.edu (128.252.135.4), ftp.uu.net
(137.39.1.9), nic.funet.fi (128.214.6.100), src.doc.ic.ac.uk
(146.169.3.7) or rana.cc.deakin.oz.au (128.184.1.4), or by e-mail
through the BITNET/EARN file servers which are not affected because
they get their files from OAK.

OAK.Oakland.Edu is the most up-to-date mirror because I maintain it, in
addition to my duties at SIMTEL20.  I make sure its mirror program runs
whenever new files are added at SIMTEL20.

The following new files are now available from OAK:

Directory: /pub/msdos/4dos/
4dos40u.zip     911118 update to 4DOS COMMAND.COM replacement

Directory: /pub/msdos/gif/
cshw841a.zip    GIF/MAC/RLE view/print, Herc/CGA/EGA/VGA/SVGA

They have been manually added to the directory list that LISTSERV and
TRICKLE use so they should now be available via e-mail as well as FTP.
Note: LISTSERV and TRICKLE users should continue to use the SIMTEL20
directory structure format in the commands to get these files.  In
other words, as far as the file servers are concerned these two files
are in the pd1:<msdos.4dos> and pd1:<msdos.gif> directories
respectively.

It is now possible to subscribe to any file provided by trickle
servers.  These include the MSDOS,MISC,CPM,UNIX and MACINTOS
directories from SIMTEL-20, OS2 directory of hobbes.nmsu.edu, and now
AMIGA directory of nic.funet.fi site.

You basically subscribe to patterns,  and whenever a new file is placed
on the ftp site, the server will deliver you a copy - before you even
ask for it, and usually before you read the announcement about it.

The commands must be sent to the closest TRICKLE server to you. Here is
a list from the documentation:

The Server Sites (listed in connection order:)

/SUB <dirnam.subdir>pattern  Allows you to subscribe to a particular
     set of files on the server. See chapter on "Subscribing to Files"
     for more info.

/UNSUB <dirnam.subdir>pattern  Terminates a file subscription. (...)

Subscribing to Files:
    This new feature  allows you to subscribe to a  'pattern' on the
server, and whenever new files that match that pattern arrive to the
server, a  /PDGET command will be  automatically entered for you, for
those files.

    Basically, you  tell the server the  directory, the subdirectory
and a 'keyword' - the first  few characters of a filename.  If a few
files match  your request, your entry is  recorded, and from there on,
if that pattern shows  up in the 'New  Files Listing' mail of  the
server, the  command /PDGET  for that file  will be entered for you.

    LIMITATIONS:  ..You are  still bound  by your  daily quotas  and
server  quotas.   The server  simply  'simulates'  that you  are
sending  /PDGET  commands to  it.   So,  if  you have  too  many
subscriptions, you MAY get 'you  issued too many commands today' error,
or  'the server's  outstanding bytes  count is  too high, cannot order
another file from  SIMTEL right now.' errors.

    The simulated  /PDGET command is assumed  to have come in  as an
interactive message to  the server, so if you are  not logged in at
that  time, you may miss  the server's reply message  - don't think
that it  did not work.  Try a /TRLIST  before ordering the file
(again).

    HOW TO USE:

    Actually, there are three new commands:
        /SUB   <directory.subdir>keyword
        /UNSUB <directory.subdir>keyword
        /SUB QUERY

    /SUB now  has double purpose -  you can still subscribe  to 'new
directory listings' announcement file  by using /SUB <directory> , but
you can also use  it with a subdirectory  option as well.  Let me give
an example, I like getting the SCAN utility whenever a new one is
available, so I can send this (and I already did :)

    /SUB <MSDOS.TROJAN-PRO>SCAN (UUE

    Now  I am  subscribed  to all  files  in the  <MSDOS.TROJAN-PRO>
directory that start with the word  SCAN.  Note that it would be
useless to subscribe to "SCAN91" since the trailing numbers keep
changing  -  in the  near  future,  no  files would  match  your
pattern.

    The UUE option  just tells the server to encode  the file for me
before sending.  It's an optional parameter.  (See the help file for
encoding options).  If you don't specify it, the server will send it
NETDATA (..if you are not domain-addressed).

    Likewise, /UNSUB removes an entry from your subscription list.

    Finally, /SUB QUERY allows you to review your subscriptions.  It
will display a list of the keywords stored for you.

    There  is  currently  no  artificial  limit  on  the  number  of
subscriptions,  and hopefully  we will  not have  to build  such
limits.  Remember: You  CAN exceed daily limits if  you have too many
subscriptions.

    Note:  This new  option also  allows for  'mirroring' of  server
archives.  If thre  are those who are working on  a server which can
receive feed  from a  TRICKLE server,  please contact  your closest
server's  administrator.   TRICKLE can  subscribe  your server to  ALL
the files  in a  subdirectory, and order  ALL new files  -   but  for
this,   you  need  the  approval   of  your administrator.

    Finally, a disclaimer: A file  subscription can be terminated by
the server maintainer, if it deemes to be too resource-consuming (such
as, if you subscribe to too many things).

For the entire help file, please send a: /HELP

command (either via interactive message, or E-Mail) to a trickle
server, such as trickle@frmop11.bitnet.

There are two discussion lists on the subject: RED-SYS@TREARN.BITNET
provides information about the server itself, whereas
RED-UG@TREARN.BITNET talks about the software provided by the server.
