ABSTRACT:
The NACS2.EXE file is a maintenance PTF for NACS2x.  The file includes NASI
v2.15 and NACS v2.14.  The NACS2.EXE file replaces PTF314.EXE.  Along with
the problems corrected by PTF 314 this file corrects a random disconnection
problem related to calls made into the program.  The file also corrects a
problem relating to ITO clearing a port that should not be cleared.

DOCUMENT #: TB.S.P328
DATE: July 6, 1992
PRODUCT: NACS
PRODUCT VERSION: 2.X
SUPERSEDES: All prior NACS/NASI PTFs for version 2.X

SYMPTOM:       Port in use cleared
               Disconnect
               OEM Registration Error
               3270 Emulation hang
               Unable to connect or very poor performance using
               Tanagram. If used with PC Anywhere IV only Port
               One was recognized.


PTF 328 will in the NetWire Library as NACS2.EXE

ISSUE/PROBLEM
1.  If a workstation hangs a NACS port it can reboot and access another
port.  In certain environments when ITO finally cleared the hung port it
cleared all ports associated with the workstations node address thereby
clearing both the idle port and the port in use.

2.  Calls made into the NACS with PC Anywhere IV LAN randomly disconnected
after a few minutes.  (it is assumed that the problem would occur with
other dial in products).

2.  NACS was designed to refuse to operate and return an "OEM Registration
Error" if it could not identify the WNIM board as having been sold by
Novell.

3.  Recent versions of NASI were conflicting with an interrupt required by
Novell's 3270 LAN Workstation.

4.  Tangram's use of Xon/Xoff flow control while connecting to Host was not
compatible with NACS/NASI.

5.  If used with PC Anywhere IV only Port One was recognized.

6.  Access Server could secure only one NACS/NASI session.

7.  ITO Timer not closing the connection.

8.  AnyWare 3.0 hangs

9.  Clear Port command and Disconnect command not working

10.  Lexis/Nexis compatibly issues

11.  Crosstalk Mark IV compatibility issues

12.  NACS server could only be downed by a reboot.

13.  NASI could only be removed from the workstation memory by a reboot.

14. Solves file transfer problems with PCAnywhere IV/LAN.

SOLUTION
1.  NASI will now check for a response and a port number after a
workstation is re-booted thereby correcting the problem.

2.  Third party host and remote software will now be allowed to work
correctly.

2.  NACS will no longer check for a Novell PAL chip on the board.  Version
2.14 of NACS will therefore work with WNIM cards from Microdyne or
Gateway.

3.  NASI will no longer impact upon the Interrupt required by Novell's 3270
LAN Workstation.

4.  The PTF corrects the problem.

5.  All ports are now recognized.

6.  More than 1 session can now be used IF this PTF is installed AND "/D
(enter)" is typed at the NASI prompt before calling out.  The /D command
activates NASI's "dynamic socket s" option allowing multiple Access Server
sessions.

7.  ITO Timer now closes the connection in all known cases.

8.  AnyWare 3.0 no longer hangs in all known situations.

9.  The commands now work in all known cases.

10.  Lexis/Nexis is very sensitive to changes in NASI.  You may have to
change versions of NASI and/or LEXIS to achieve a match.

11.  Function Call 16h return made compatible with Crosstalk Mark IV,
Network Version.

12.  The NACS Server can now be downed by typing "DOWN".

13.  The UNLOAD utility is included in this PTF.  Type "UNLOAD" to remove
NASI.EXE from memory.

14.  Updates the transmit, receive and external status bytes when an ACK is
sent.

NEW VERSION
The installation of this PTF converts your NACS to Version 2.14 and NASI to
Version 2.15.  It may be installed on top of any version 2.06, 2.07, 2.08,
or 2.09 NACS/NASI with files of an earlier date.  NACS 2.14 and NASI 2.15
are designed to be used together exclusively.  Do not attempt to mix and
match NACS and NASI versions unless specifically advised to do so by a
Novell Communications Products Division technician.

TO USE PTF 328  (see NOTE below)
1. Run "NACSINST NACS.EXE"* with your PRESENT NACS (that is, without the
PTF).
2. Write down the resulting configuration.
3. Copy the PTF over the old NACS files.
4. Run "NACSINST NACS.EXE"* again.
5. Enter the configuration information from step 2.

NOTE: If you had previously installed PTF 314 you need only copy the new
NASI over the old NASI.

* Use the NACSINST.EXE you already have.
