A new version of NCSA Telnet with TN3270 support is now
available via anonymous ftp from omnigate.clarkson.edu (128.153.4.2)
from the directory /pub/ncsa2.2tn
This is the readme file from that directory.
Version 2.2TN is an upgraded copy of version 2.2C with support
for a single Tn3270 session concurrent with simultanous
non-3270 telnet sessions. A full description of new features
and bug fixes are included at the end of this notice.
A similar version without the 3270 support is also included.
It has all the bug fixes and other enhancements as version 2.2TN
but without the 3270 support, its called version 2.2D.
The following files are available:

ncsabin.tar.Z contains the binaries for tn3270.exe, telbin.exe
telpass.exe, ftpbin.exe, tncpp.exe, a sample
config.tel and various 3270 support files.
tn3270.exe is identical to telbin.exe except that
it has 3270 datastream support.
ncsasrc.tar.Z contains the source for all programs, requires
turbo C 2.0.
readme this file
telnet.doc.Z contains updated documentation. This is version 2.2C
documentation with additional margin comments
describing new features.
Note!: Both tar files are binary copies of PC source. If you untar
the source on a unix system, you will have to strip off trailing
CR's and a ^Z at the end of each file. Also, the commonly available
tarread.exe can not extract binary images, it will extract the
source correctly, but should not be used to extract the executables.
Omnigate is no longer providing packet drivers, you can get them
from sun.soe.clarkson.edu:/ka9q/drivers.exe Be advised that
the old SLIP8250 driver has a bug and will not work with this
version of telnet.
This software is available via E-Mail. For information on how
to obtain a copy via email, send mail as follows:
mail archive-server@sun.soe.clarkson.edu
Subject:
path <your return address in internet form goes here>
send ncsa2.2tn Index
^D
The archive server has 8 uuencoded files that can be reassembled
into ncsabin.tar.Z and 13 uuencoded files that can be reassembled
into ncsasrc.tar.Z. The documentation is also available via
the archive server. In this distribution no uuencoded file
is larger than 75K bytes. Be sure to use the path command in
your request to the archive server to ensure proper reply addressing.

The following is updatetn.doc - describes updates and bug fixes to this
version.
-----------------------------------------------------------------------
NCSA Version 2.2D and Version 2.2TN bug fixes and enhancements
This file describes bug fixes from version 2.2C and enhancements
added to make version 2.2TN/D. Enhancements added apply to both
2.2D and 2.2TN except where noted. Bug fixes apply to both equally.
Enhancements:
1. Version 2.2TN (only) now supports a single 3270 connection
to VM hosts concurrent with simultanous regular telnet sessions.
The 3270 code is based on version 4.1.1 of Unix tn3270
developed by Greg Minshall of Berkeley and is Copyright
(C) 1988 by the Regents of California.
(this is the only portion of NCSA Telnet 2.2TN that is not
public domain)
TN3270 emulation supports 25, 32 and 43 line 3270 screens
as well as 7171 datastreams to the TEK screen, VTscreen or
capture file.
2. Telnet negotiation options are now expanded, the console
provides detailed indications of the negotions. New options
supported:
Terminal Type (will send VT102, or IBM-3278)
NAWS (Notify About Window Size) to automatically inform
the host about your window size (43 lines, 35 lines etc).
EOR (for 3270)
Binary (only in 3270 mode, normal telnet connections refuse
binary mode (due to limitations in CMU-TEK-TCP for VMS)
3. Program Status, reports on stack depth used and remaining
free memory.
4. Ansi set color escape sequences are now supported, as well as
Ansi print through and screen dump escape sequences.
(Thanks to David Camp of Washington University Medical School).
5. Screen Dump (ALT-D) to capture file.
6. The Packet Driver interface now supports SLIP mode,
but requires packet drivers compatible with FTP specification
version 1.08 or above.
7. A built in screen saver is provided, with variable delay from
0 to 60 minutes (0 disables the screen saver).
8. Escape to dos (ALT-E) works from server mode.
9. Telnet now automatically switches into 43 or 35 line mode
if run on an EGA and the -l option was specified. 50 line mode
works under MSwindows, but is not automatically supported
under telnet.
10. The parameters menu can now set BOLD and BLINK for foreground
and background colors.
Bug Fixes - This section describes bugs fixed since version 2.2C
1. A change was made in the lowwater/receive window code to
cause an updated rwindow packet to be sent to hosts when the
water mark passed the halfway point. Previously an update
packet was sent after passing the 600 byte mark. This improves
performance when cat'ing large files to the screen, and
removes long pauses that had occured previously.
2. The FTPBIN client now works. There is a limitation in the
ni5210 driver which causes it to crash if maxseg is larger than
1098 bytes. The maxseg now has an upper limit of 1024 for all
cards. (this should be made more robust in the future, pending
decisions by FTP software on how the Packet Driver is to handle
maxseg)
3. The domain name lookup routines, when using a domainslist, would
skip to the next search entry if a lookup timeout occured.
It has been fixed to skip to the next entry only if a 'host not found'
error is returned.
4. The parameters menu used to save the parameters even if <ESC>
was pressed (where normally F1 is used to save the params).
Also, there was a bug that would keep the terminal type from
being reset to VT102 if it was set to DUMB. Both problems
have been fixed.
5. There was a problem in the FTP server when performing an
mget fred/*. The files returned to the host would have a \
rather than a /. This has been fixed. Also, the server would
attempt to upload the directories . and .. during an mget.
6. When exiting telnet in 43 line mode, often telnet would not
correctly reset the video configuration. This has been fixed,
and now works correctly for both 43 and 35 line operation.
