New versions of the tn3270 and mset commands, used to logon to CMS from
unix, have been installed in /usr/new on all computer center Vaxen and
Suns.

Significant changes to tn3270 are:

o   The original version of tn3270 emulated an IBM 3277 terminal.  This is
    an out-of-date terminal, and is no longer supported in some IBM
    environments.  The new version of tn3270 emulates an IBM 3278
    terminal, which is a more recent IBM terminal.  The new version of
    tn3270 will emulate different models of the IBM 3278, depending
    on the size of the user's terminal.  The available terminal models
    and screen sizes are documented in "man new tn3270".

o   This version of tn3270 (and mset) allow the user to send an EBCDIC cent
    sign to the CMS host with the new map3270 "centsign" entry.  In addition,
    TEST REQUEST and CURSOR SELECT (IBM 3270 functions) now work reliably.

o   This version of tn3270 handles "autoskip" fields correctly.

o   This version of tn3270 will work even if the terminal (or window) on
    which tn3270 is running has a line width of more than 80 columns.

o   Clearing all local tab stops now clears "home" and "right margin"
    (which is the way the Series/1 works).

o   Tn3270 and mset now use an environment variable "KEYBD", if it
    exists, to decide which entry in /etc/map3270 to use for the
    user's terminal.  If "KEYBD" is not defined, then "TERM" is used.

o   A bug in the implementation of the 3270 order "Repeat to Address" (RA)
    has been fixed.

o   Mset now has new options "-picky" and "-shell"; see "man new mset".

o   Tn3270, when terminating (or going into command mode) now sends
    the termcap :ve:, :ke:, and :te: (if they exist) to the terminal.
    In addition, if the screen was in standout mode, this mode is
    cleared before terminating (or going into command mode).  See
    termcap(5).

o   Tn3270 now attempts to use the termcap :md: and :me: strings for
    highlighting instead of :so: and :se: (:so: and :se: are still used
    if :md: and :me: do not exist).  See termcap(5).

o   Various bugs giving rise to infinite loops dealing with "unformatted"
    screens have been fixed.

o   The base telnet portion of tn3270 (see telnet(1)) has been upgraded
    to the 4.3 telnet.  This has fixed many bugs where tn3270, in telnet
    mode, violated the ARPAnet TELNET specification.  In addition, the
    command structure for tn3270 is that of the 4.3 telnet, rather than
    the 4.2 telnet (which was the command structure for the older versions
    of tn3270).

o   A new command, transcom, has been added.  This allows users to write
    (somewhat intricate) programs which can communicate, in ASCII, with
    programs in the IBM host that talk "transparent" mode.  This may be
    useful for communicating graphics data to the terminal.  For more
    information on this feature, please see "man new tn3270" (and, on the
    Sun systems, "man tk3270").
