.h1;Copying the Software

Before you run SW/200-A/BSC/SDLC Version 22000 on the CS/210,
make a copy of the distribution diskette using the following
procedure:

1.  Attach a terminal to port 0 of the CS/210.

2.  Make sure that there is no diskette in the disk drive.  Then
power on the CS/210.  The Self Test LED turns on.

3.  After the Self Test LED turns off, the Boot State LED lights
briefly.  After the Boot State LED turns off, the Self Test
LED flashes on and off.  Press the hardware interrupt switch
on the CS/210.  For further information on the location and
operation of the hardware interrupt switch, refer to Section
2 of the Series/200 Installation Guide.

4.  Press the Return key.  The monitor prompt (>) appears.

5.  Perform firmware configuration on the CS/210 if necessary.
Otherwise, go on to the next step.

Refer to Section 3.8 of the Series/200 Installation Guide for
further information on firmware configuration.  After you
perform firmware configuration, return to the monitor prompt
(>).

6.  At the monitor prompt (>), type the following command to make
a copy of the distribution diskette.

    co <n>

where n is the number of copies to be made.  The following
message appears on the screen:

    insert master and hit the Return key

7.  Insert the SW/200-A/BSC/SDLC Version 22000 distribution
diskette in the disk drive.  Then press the Return key.

The following messages appear on the screen if the read
completes successfully:

    reading ... OK
    insert copy 1 and hit the Return key

In the actual display, the number in the message may vary
according to the number of copies you have made.  If the
message "read error" appears instead of the message "OK",
contact an authorized 3Com service representative for help.

8.  Remove the SW/200-A/BSC/SDLC Version 22000 distribution
diskette from the disk drive, and store it in a safe place.
Insert a blank, 135 TIP, double-sided, double-density, 3 1/2-
inch diskette in the disk drive.  Then press the Return key.

If the copy completes successfully, the following messages
appear on the screen:

    formatting ... writing ... verifying ... OK
    copy completed.

9.  Remove the diskette from the disk drive, and label it "SW/200-
A/BSC/SDLC Version 22000."  You can now use the newly made
copy of SW/200-A/BSC/SDLC Version 22000 on your CS/210.

After you install the software, you will have to define the
global parameters, clearinghouse names, macros, and port
configurations.

                     ** NOTE **

If you use the configurations, macros, and global files
copies from a previous version of SW/200-A/BSC/SDLC, you must
use the SETD command to set the value of teh AUditTrailType,
TimeZone, DaylightSavingsTime, NetMapBroadcast, and MacType
parameters after booting the CS/210.

.h1;Sysgen

System generation can be performed on the CS/210 running SW/200-A/
BSC/SDLC Version 22000.  The Sysgen parameters and default values
for the CS/210 are the same as for the CS/200.  Refer to the
sections on the CS/200 in the Configuration Guide (February 1988
edition) for further information on the Sysgen program.

To start the Sysgen program, follow these steps:

1.  Attach a terminal to port 0 on the CS/210.

2.  Make sure that there is no diskette in the disk drive on the
CS/210, and then power on the CS/210.  The Self Test LED
turns on.

3.  After the Self Test LED turns off, the Boot State LED lights
briefly.  After the Boot State LED turns off, the Self Test
LED flashes on and off.  Press the hardware interrupt switch
on the CS/210.  For further information on the location and
operations of the hardware interrupt switch, refer to Section
2 of the Series/200 Installation Guide.

4.  Press the Return key.  Then the monitor prompt (>) appears.

5.  Perform firward configuration if necessary.  Otherwise, go on
to the next step.

Refer to Section 3.8 of the Series 200/ Installation Guide
for further information on firmware configuration.  After you
perform firmware configuration, return to the monitor prompt
(>).

6.  Insert in the disk drive the SW/200-A/BSC/SDLC Version 22000
diskette that you created in the software copy procedure.

7.   At the Monitor prompt (>), type the following command to
 invoke the Sysgen program:

     bt 1d

The Sysgen program is invoked, and the Main Menu is
displayed.  Refer to the Configuration Guide for further
information on the Sysgen program.

.h1;New Features

SW/200-A/BSC/SDLC Version 22000 includes the new features
described below.  These features were not available in previous
versions of CS/200 software.

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 NCS/150 does not yet support this feature.

*   A new global parameter, AUditTrailType, is available.  This
parameter 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/150 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 CS/210 firmware can be figured so that the CS/210 is
booted from a local diskeete or a Network Control Server.
The boot source determines the origin of the macros,
configurations, and global parameters.  For more information
on firmware configuration, refer to the Series/200
Installation Guide.

SW/200-A/BSC/SDLC Version 22000 runs on a CS/210 that is
booted from a local diskette.  Macros, configurations, and
global parameters can also be stored on and retrieved from
the local diskette.

*   The SHow AllSessions command, which displays a list of all
physical ports on the Cs/210, 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 CS/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 previous versions of CS/200
software, have been fixed in SW/200-A/BSC/SDLC 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 CS/210.

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

*   The Sysgen parameter, SPP Minimum Window Size, can now be set
to all of its possible values.  Previously, it could not be
set to 2 or 1.

*   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 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 form 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.

*   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 Version 22000 has the following limitation:

*   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
