w8sdz@WSMR-SIMTEL20.ARMY.MIL (Keith Petersen) (03/23/89)
A new version of NCSA Telnet with TN3270 support is now available from
Simtel20.
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 in directory pd1:<msdos.ncsatelnet>
NCSABIN.ARC 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.ARC contains the source for all programs, requires
turbo C 2.0. The ARC files within this archive
should each be placed in their own directories
with the same name as each archive.
README.TXT this file
NCSADOC.ARC contains updated documentation. This is version 2.2C
documentation with additional margin comments
describing new features.
DRIVERS.EXE is a copy of drivers from sun.soe.clarkson.edu's
directory pub/ka9q/drivers.exe
Be advised that the old SLIP8250 driver has a bug and will not work
with this version of telnet.

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.
