SUBJECT:     SW/1-A/BSC/SDLC Version 20060

DATE:        March 30, 1987

Enclosed is the SW/1-A/BSC/SDLC Version 20060 diskette. This
diskette is your distribution copy of SW/1-A/BSC/SDLC Version
20060 and should be used only to copy the system software onto
the master diskette. The master may then be used to update the
current working diskette.

If your current working diskette is SW/1-A/BSC Version 17100 up
to SW/1-A/BSC/SDLC Version 20030, Bridge recommends the following
procedure to update your system to Version 20060 without losing
port configurations, macros, and clearinghouse names. Otherwise,
refer to pages 3 and 4 for the updating procedure.

1.  Connect your terminal to the console port of the CS/1.

2.  Press the Reset switch.

3.  Make a backup copy of the distribution diskette using the
following command:

> co <n> <CR>
.br;where n is the number of copies to be made.

4.  The following message appears on the screen:

Insert master and hit return key
Insert the SW/1-A/BSC/SDLC Version 20060 diskette in the disk
drive.  After you press the return key, the following
messages appear on the screen if the read completes
successfully:

.br;Reading ...  OK Insert copy #n and hit return key
If the message "read error" appears instead of the message
"OK", contact an authorized Bridge service representative for
assistance.

5.  Remove the SW/1-A/BSC/SDLC Version 20060 diskette from the
disk drive. Insert a blank, 48 TPI, double-sided, double-
density diskette in the disk drive, then press the return
key.

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



.br;writing ... verifying ... OK copy completed
Remove the diskette from the disk drive, and label it "SW/1-
A/BSC/SDLC Version 20060". Store the distribution diskette in
a safe place.

7.  Insert your current working diskette in the disk drive. Then
enter the following command after the prompt:

> r 20B 3000 c600 <CR>

8.  Remove your working diskette and insert the SW/1-A/BSC/SDLC
Version 20060 diskette in the disk drive. Enter the following
commands to copy the port configurations, macros, and
clearinghouse to the Version 20060 diskette.

> w 26e 3000 200 <CR> > w 216 3200 400 <CR> > w 219 3600
1000 <CR> > w 225 4600 2a00 <CR> > w 23a 7000 400 <CR> >
w 23d 7400 4000 <CR> > w 26d f400 200 <CR>

9.  Repeat steps 7 and 8 for each system being updated.

If you are currently running SW/1-A/BSC/SDLC Version 2005x (where
x represents a number from 0 to 9), use the following procedure
to update your system to SW/1-A/BSC/SDLC Version 20060:

1.  Connect your terminal to the console port of the CS/1.

2.  Press the Reset switch.

3.  Back up the distribution diskette by following steps 3
through 6 on pages 2 and 3.

4.  Then copy the distribution diskette onto your SW/1-A/BSC/SDLC
Version 2005x master diskette using the following command
(provided the MCPU PROM on your CS/1 MCPU board is revision 9
or earlier):

> co -p <n> <CR>
where n is the number of updated diskettes to be made.

5.  When the system prompts for the first and last block numbers,
enter the numbers as follows:

> First block?  0 <CR> > Last block?  215 <CR>



6.  If the MCPU PROM on your CS/1 MCPU board is revision 1B or
later, use the following command to copy the distribution
diskette onto your SW/1-A/BSC/SDLC Version 2005x master
diskette:

> co -p 0 215 <CR>

7.  The following message appears on the screen:

Insert master and hit return key
Insert the SW/1-A/BSC/SDLC Version 20060 diskette in the disk
drive. Then press the return key. The following messages
appear on your screen if the read completes successfully:

Reading ...  OK Insert copy #n and hit return key
If the message "read error" appears instead of the message
"OK", contact an authorized Bridge service representative for
assistance.

8.  Remove the SW/1-A/BSC/SDLC Version 20060 diskette and insert
the  SW/1-A/BSC/SDLC  Version 2005x diskette in the disk
drive, then press the return key.

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

writing ...  verifying ...  OK copy completed

10. Remove the diskette from the disk drive and label it "SW/1-
A/BSC/SDLC MASTER VERSION 20060". Store the distribution
diskette in a safe place.
If you are not currently running SW/1-A/BSC Version 17100 or
later, use the following command to copy the new release to a
blank, 48 TPI, double-sided, double-density diskette:

.br;> co <n>
where n is the number of copies to be made.

You will need to rebuild the clearinghouse names, macros, and
port configurations.

If you have an SIO-16 in the CS/1, the  following  configurations
must be used:

1.  For the CS/1 with one  or  more  SIO-16s,  an  EC/2  must  be
installed  in  the  CS/1. In addition, the MCPU PROMs must be
M1MMON Revision 1G or later.

2.  For the CS/1 with three or four SIO-16s, the MCPU board  must
be  upgraded  to 12MHz. One or two SIO-16s can be used with a
10MHz MCPU board.

New Features

The following features, which were not present in SW/1-A/BSC/SDLC
Version   20050  or  earlier,  have  been  implemented  in  SW/1-
A/BSC/SDLC Version 20060:

1.  In addition to the SETDefault command, the SET command can be
used  to  alter  the  buffer  size of an individual port. For
instance, to change the current buffer size of a port  to  56
bytes, type:

.br;set BUffersize = 56
To change the buffer size of the host, the REMoteSET  command
can  be  used  with the same syntax shown above.  Setting the
buffer size to be smaller than the system buffer size,  which
is  usually  82  bytes,  will actually create a buffer of the
specified size. If the specified value is  greater  than  the
system  buffer  size,  more buffers of the system buffer size
will be created instead of a bigger buffer.

The SET command will not take  effect  immediately  during  a
session.  The  additional buffers created by the command will
not be used until the buffers currently allocated to the port
have been exhausted.

2.  It now takes 4 seconds for the Communications Server to
deliver the audit trail data to the NCS. It used to take 90
seconds.

The 4-second timer can be sysgenned. This is done by
modifying the Statistics Monitor timer value. Please refer to
the Configuration Guide for further information.

3.  The server will accept from the netmap packet a clock value
that is lower than the current value. For example, if the
clock on the NCS is set back to year 1970, all the system
clocks of the servers on the network will be changed within
45 seconds to this new value.



Bugs Fixed

The following problems have been corrected in SW/1-A/BSC/SDLC
Version 20060:

1.  The audit trail records now show the actual number of rotary
ports used. In the past, the rotary ports used count was
always zero according to the audit trail records.

2.  It is no longer possible for a port to be trapped in the
WAIT-FOR-CONNECT state forever or for the PVC (Permanent
Virtual Circuit) to suddenly stop working.

3.  The data link drivers can now detect all known deadlock
situations properly.  Running the servers on a noisy network
will not crash the servers or cause the servers to drop from
the netmap.  However, the PROM on the EC/2 board must be
M0EDL2 01A or later for this to work.

Known Problems

The following is a list of current problems in SW/1-A/BSC/SDLC
Version 20060:

1.  If you have not updated all of your CS/1s to SW/1-A/BSC/SDLC
Version 20000 or later, a connection from a CS/1 that runs
SW/1-A/BSC Version 17100 or SW/1-A/BSC/SDLC Version 18610 to
a CS/1 that runs SW/1-A/BSC/SDLC Version 20000 or later may
cause a delay of approximately four seconds.

2.  If the FlowControlTo and FlowControlFrom parameters are both
set to None, resetting one of the parameters to XonXoff or
ENQACK causes the other to be automatically set to XonXoff or
ENQACK. Note that this problem does not occur for the other
two options (None and CTSRTS).

3.  If your working diskette was SW/1-A/BSC/SDLC Version 20030 or
earlier before being updated to Version 20060, the
LogoffString may contain garbage characters when the software
is first booted. In order to eliminate these garbage
characters, use the following command:

SETDefault LogoffString = ""

4.  Due to a memory limitation, the SHow CONFiguration and SHow
MACro commands no longer display output in alphabetical
order.

5.  On the SIO-16's ports, the help menu of the BAud parameter
displays LowAutoBaud and HiAutoBaud as options of this
parameter. However, the SIO-16 supports only single-range



autobaud. Whether you set the BAud parameter to HI or LO will
not affect the baud rate, which will range from 50 to 38.4K
to match the terminal's baud rate.



6.  There are no Clear to Send (CTS) and Request to Send (RTS)
lines for the SIO-16. However, on the SIO-16's ports, the
help menu of the FlowControlTo and FlowControlFrom parameters
displays CTSRTS as an option of these parameters.

Features of Synchronous Data Link Control (SDLC) Interface

To activate the bit-synchronous parameter menu, the user must set
the LinePRotocol parameter to BITsynchronous (provided the SIO-
SMS or SIO-STS board installed in the CS/1 has M1 SYNC SIO PROMs
of Revision 1A or later).

The bit-synchronous software supports third-party connections
only. In order to establish a third-party connection, the network
manager must make the connection via an asynchronous terminal
connected to the network. Alternately, the interconnection
service can be established by the use of the "init"  macro. The
"init" macro must be installed by the network manager from an
asynchronous terminal connected to the network.

Since the Connection Service commands are not available directly
to a bit-synchronous port, parameters for a bit-synchronous port
are set remotely from an asynchronous terminal. Refer to the
Configuration Guide for the configuration instructions.

Procedure to Sysgen SW/1-A/BSC/SDLC Version 20060

Following is the procedure for running the sysgen program on the
CS/1. For further information on menu displays and parameters,
please refer to the Configuration Guide. System generation is not
required before installing the software. It is used to alter the
values of certain parameters. Bridge does not recommend altering
those values by sysgen without a specific need.

1.  Connect a terminal to the console port.

2.  Insert the SW/1-A/BSC/SDLC Version 20060 diskette in the CS/1
disk drive, then press the Reset switch. The CS/1 displays
the following messages:

Power-up V1.0 MCPU-passed   <MCPU Firmware Version> EC-
passed     <Ethernet address>   <EC Firmware Version> SIO
# 1 - passed <SIO Firmware Version> SIO # 2 - passed (or
not present) SIO # 3 - passed (or not present) SIO # 4 -
passed (or not present) Bridge Communications MCPU
Monitor



3.  After the above messages, the system displays a ">" prompt.
Enter "gn" and press the return key.

4.  The CS/1 displays the Sysgen Utility V2.0 menu and a message
at the bottom of the screen asking you to make a selection.

5.  Enter 1 to select View/Alter Module Parameters, then press
the return key.

The CS/1 then displays the Module Select Menu and a message
at the bottom of the screen asking you to make a selection.

6.  To display a parameter module, enter the number of the module
as it appears in the Module Select Menu, then press the
return key.

7.  After the list of parameters appears on the screen, you can
change the value of a parameter by entering its number. Then
enter the new value of the parameter at the prompt and press
the return key.

8.  Press <ESC> to return to the Module Select Menu.

9.  After system generation is complete, enter 2 to save all the
parameters.

10. Enter 3, then press the return key to exit to the monitor.
