Whenever a command is referenced in this release memo, assume
that the Return key should be pressed after you type each
command.


.h1;Installation

Because your Series/200 server is booted from an NCS/1, install
SW/200-A/BSC/SDLC-NCS/1 on the NCS/1.  Refer to Section 3.5 of
the NCS/1 Installation and Operation Guide for this procedure.

If your Series/200 server is not already bound to the NCS/1, use
the BInd command to enable your Series/200 server to boot from
the NCS/1.  Refer to Section 5.2 of the NCS/1 Installation and
Operation Guide for information on the BInd command.

.h1;New Features

The following features, which were not available in SW/200-A/BSC/
SDLC-NCS/1 Version 20080, have been implemented in SW/200-A/BSC/
SDLC-NCS/1 Version 22000.

Because these features were first supported in TCP/IP software
Version 20000, the Connection Service User's Guide states that
they are available only in TCP/IP protocol software Version 20000
or later.  Please disregard these statements when referring to
this guide for further information on these features.

*   You can define macros containing conditional statements.

*   The ZeroMacros command, which clears the contents of the
macro cache on the local server, is now available.

*   Universal Time is now available for network communications
spanning different time zones.  Two new global parameters
have been implemented to support this feature.

The DaylightSavingTime parameter specifies the displacement,
in hours or minutes, from non-Daylight Savings Time.  The
TimeZone parameter specifies in hours or minutes how far west
the server is from Greenwich.

The Network Control Servers do not yet support this feature.

*   A new global parameter, AUditTrailType, is available.  It
specifies the format of the time-stamp for audit trail
messages.  The two formats are Local time and Universal time.

*   A new parameters, NetMapBroadcast, has been added.  This
parameter, which can be set to ON or OFF, determines whether
the Series/200 server broadcasts its netmap packets.

*   A new parameter, MacType, has been added.  Its possible
values are IEEE and Enet.

This parameter determines the type of Media Access Control
level protocol to be used.  If this parameter is set to Enet,
all data link packets are sent as Ethernet packets.  If it is
set to IEEE, all data link packets are sent as IEEE 802.3
packets.

In addition to the features described above, SW/200-A/BSC/SDLC-
NCS/1 Version 22000 has the following new features, which are not
described in the Connection Service User's Guide:

*   A new Connection Service command, PIng, enables you to
determine whether a specified host is operating without
having to form a connection to the host.

This command uses the ECHO protocol to send echo request
packets to the specified address.

The following is the syntax for the PIng command:

    PIng <clearinghouse name | address > [<timeout>]

You may specify a physical address or a clearinghouse name.
The timeout value specifies the length of time in seconds
that the Series/200 server waits for a response from the
addressed host.  The default timeout value is 20 seconds, and
the maximum timeout value is 300 seconds (five minutes).

All Communications Servers running XNS protocol software
versions that support the PIng command respond to the echo
request by sending an echo response packet.  If the host
responds within the specified timeout period, the message
"Host is alive" is displayed.  If the host does not respond
within this period, the message "Host is not responding" is
displayed.

To interrupt the PIng command, press the Break key.

*   The SHow AllSessions command, which displays a list of all
physical ports on the Series/200 server, now also shows the
originating address of a connection when it is a passive-end
connection or an interconnection.

*   When a Data General terminal port receives a host-initiated
break signal, the Series/200 server terminates any pending
flow control to that port.

*   When the ECMChar parameter on a Data General terminal is set
to a character, the DLE character is processed.  When the
ECMChar parameter is disabled, the DLE character is passed as
data.

.h1;Bugs Fixed

Certain problems, which existed in SW/200-A/BSC/SDLC-NCS/1
Version 20080 or earlier, have been fixed in SW/200-A/BSC/SDLC-
NCS/150 Version 22000.  These problems and their resolutions are
described below.

*   The audit trail record code for excessive retransmission, ER,
is now sent to a Network Control Server if the SPP
retransmission count exceeds 200 within an hour.

Previously, this information was not recorded on the NCS
because the SPP retransmission count failed to exceed zero,
regardless of the number of actual SPP retransmission.

*   The ReaD command now works properly for the port configured
as the last virtual port on the Series/200 server.

Previously, this command replaced the in-memory default
parameters of the last virtual port with those from a
specified file on the system diskette, but failed to
automatically copy the new in-memory parameter

*   Previously, if the FlowControlFrom and FlowControlTo
parameters were both set to None, resetting one of the
parameters to Xon_Xoff or ENQ_ACK caused the other to be
automatically set to Xon_Xoff or ENQ_ACK.  This problem has
been corrected and the FlowControlFrom and FlowControlTo
parameters can be set independently.

*   SW/200-A/BSC/SDLC-NCS/150 Version 22000 attempts to
establish connections to permanent virtual circuits (PVCs)
according to the order in which the connection requests are
received.  Previously, priority was always given to the
attempt to connect to the lowest-numbered PVC.

*   The StopBits parameter can now be set to any of its possible
values.  Previously, if you attempted to set this parameter
to 1.5, the screen displayed an error message.

*   The optional parameter, (<address>), is now included in the
syntax of all commands displayed in the Global Network
Manager help menu.  Previously, this was omitted from some
commands in the display.

For example, the syntax for the UNSave command is now
displayed in the Global Network Manager help menu as follows:

    UNSave (<address>) <filename>

*   You can now define a permanent virtual circuit using a
combination of a clearinghouse name and a port number.  The
address string specifying the clearinghouse name and port
number must not contain more than 12 characters.  For
example, the following command defines a permanent virtual
circuit from port 25 on the source server to the address
"host7!128":

    SETD (!25) pvc = "host7!128"

*   Previously, if the value of the ECHOMask parameter included
control characters, some characters (e.g., backspace) did not
function normally in Command mode.

This problem has been corrected.

*   A Global Network Manager can execute macros either from
remote mode or by using the following command syntax:

    DO <address> <macro name>

In addition, the Global Network Manager help menu now
includes the syntax for entering this command.

Do not use this command to execute a macro containing an
infinite loop or one that takes a long time to execute.  The
macro is aborted after one minute of execution to prevent it
from locking up the remote capability of the Communications
Server.

If you need to execute such a macro, connect to network
management virtual port 136 on the Communications Server and
then type the following:

    DO <macro name>

*   The X.25 host no longer hangs when you type the following
commands to initiate a connection from a Series/200 server to
the host across a GS/1-X.25:

    Connect <host address> ECM
    RES

When you enter the RESume command, the Series/200 server
sends back the response to the "read parameter" packet from
the X.25 host, and your terminal successfully enters Data
Transfer mode.

*   The global-network-manager form of the SHow STATistics -S
command now displays correct error statistics for the
network.  Previously, this command always displayed zero
errors.

.h1;Limitations

SW/200-A/BSC/SDLC-NCS/1 Version 22000 has the following
limitations:

*   Only three echo requests may be outstanding at any given
time.  If more than three users simultaneously enter the PIng
command, the following message appears:

    Can't Ping now - try later

*   System Generation is not available in SW/200-A/BSC/SDLC-NCS/1
Version 22000.
