DECnet-Plus for OpenVMS provides additional functionality for the
HOST option of the SET verb.
| 1 - Set Options |
These are the SET command options supplied by DECnet-Plus for
OpenVMS:
Option Function
HOST/MOP Connects your terminal to a remote system
by way of the current host processor using
the MOP protocol.
HOST/VTP Connects your terminal to a remote system
by way of the current host processor using
the OSI Virtual Terminal protocol.
HOST/X29 Connects your terminal to a remote system
by way of the current host processor using
the X.25 software and the CCITT X.29
protocols.
| 2 - HOST |
Connects your terminal (through the current host processor) to
another processor, called the remote processor.
Format
SET HOST remote-system
2.1 - Parameter
remote-system
Specifies the name of the remote processor to which you will
connect.
2.2 - /MOP
Connects your system to a remote system using the MOP protocol.
Format
SET HOST/MOP client-name
2. 2.1 - Parameter
CLIENT
Specifies the name of the MOP CLIENT entity which describes
the remote system that is the target of the console carrier
request. This is an optional parameter. If omitted, you
must specify the /CIRCUIT and /ADDRESS qualifiers.
2. 2.2 - Qualifiers
2. 2. 2.1 - /ADDRESS=lan-address
Specifies the LAN address of the remote system.
2. 2. 2.2 - /BREAK=break-character
Specifies the character which is to be recognized as a request
to send a MOP Break protocol command to the remote system.
Pressing the Ctrl key and this character transmits a MOP Break
to the remote system. The default character is \.
2. 2. 2.3 - /CIRCUIT=circuit-name
Specifies the name of the MOP CIRCUIT entity over which the
request should take place.
2. 2. 2.4 - /DISCONNECT=disconnect-character

to terminate the connection with the remote system. Once the
connection is established, pressing the Ctrl key and this
character terminates the connection. The default character is ].
2. 2. 2.5 - /VERIFICATION=hexidecimal-digits
Specifies the service password of the remote system. A
verification has 16 hex digits. If less than 16 digits are
specified, MOP will pad with zeros on the right.
2.3 - /VTP
Connects your system to a remote system utilizing the OSI Virtual
Terminal Protocol.
Format
SET HOST/VTP alias
2. 3.1 - Parameter
alias
Specifies the name of the remote VT application that you wish
to connect to. This name can be an alias in the
SYS$COMMON:[SYSEXE]ISOAPPLICATIONS.DAT file, or it can be the
X.500 Distinguished Name of the remote VT application enclosed
in quotes.
2. 3.2 - Qualifiers
2. 3. 2.1 - /BREAK
/BREAK=break-character
Selects the break character. The break character is used to
generate a break on lines that expect a break rather than a
carriage return. To generate a break, press Ctrl/break-character.
The break character can be any ASCII character between @ and z.
You cannot select a character currently defined as either the
command character (see the description of the /COMMAND=command-
character qualifier) or the disconnect character (see the
description of the /DISCONNECT=disconnect-character qualifier).
The ASCII characters between @ and z include the alphabetic
characters in both upper and lower cases, the "at" sign (@),
the backslash (\), the right bracket (]), the circumflex (^),
the underscore (_), and the grave accent (`).
By default, the break character is the right bracket (]).
2. 3. 2.2 - /COMMAND
/COMMAND=command-character
Selects the command character. The command character is used to
access VT command mode by pressing Ctrl/command-character.
The command character can be any ASCII character between @ and z.
You cannot select a character currently defined as either the
break character (see the description of the
/BREAK=break-character qualifier) or the disconnect character
(see the description of the /DISCONNECT=disconnect-character
qualifier).
The ASCII characters between @ and z include the alphabetic
characters in both upper and lower cases, the "at" sign (@),
the backslash (\), the right bracket (]), the circumflex (^),
the underscore (_), and the grave accent (`).
By default, the command character is the "at" sign (@).
2. 3. 2.3 - /DISCONNECT
/DISCONNECT=disconnect-character
Selects the disconnect character. The disconnect character is
used to abnormally terminate VT association with the remote
system by pressing Ctrl/disconnect-character.
The disconnect character can be any ASCII character between @
and z. You cannot select a character currently defined as
either the break character (see the description of the
/BREAK=break-character qualifier) or the command character (see
the description of the /COMMAND=command-character qualifier).
The ASCII characters between @ and z include the alphabetic
characters in both upper and lower cases, the "at" sign (@),
the backslash (\), the right bracket (]), the circumflex (^),
the underscore (_), and the grave accent (`).
By default, the disconnect character is the "backslash" (\).
2. 3. 2.4 - /LOG
/LOG[=filespec]
/NOLOG (default)
Controls whether a log file of the entire session is kept. If you
use the /LOG qualifier without the file specification, the log
information is stored in the file SETHOST_VTP.LOG.
2. 3. 2.5 - /PROFILE
/PROFILE=profile-name
Specifies the Virtual Terminal profile to be used when
establishing the association. The following profiles are
currently supported:
o Generalized_Telnet (default)
o Telnet
o Transparent
o Amode_default
2. 3. 2.6 - /STATISTICS
/STATISTICS
/NOSTATISTICS (default)
Provides statistics on the VT association, including CPU usage,
pagefaults, and I/O counts.
2. 3.3 - Example
$ SET HOST/VTP ITALIC
Username: BROWN
Password:
Welcome to VAX/VMS Version 5.4 on node ITALIC
.
.
.
$ LOGOUT
BROWN logged out at 19-APR-1991 15:04:25.27
%VT-S-END, Control returned to local end system
In this example, the name of the local node is CASLON. This SET
HOST/VTP command connects the user terminal to the processor at
the network node named ITALIC. The remote processor then prompts
for user name and password. Use the normal login procedure to
log in to the remote processor.
2.4 - /X29
Enables a connection to a host-based PAD using the X.29 protocol.
Format
SET HOST/X29 node-name
When you are first connected to the PAD, your terminal is in
data-transfer mode. You can change to PAD command mode by typing
the appropriate escape character (usually <CTRL/P>). In command
mode you can obtain further help on the PAD (by typing HELP).
2. 4.1 - Qualifiers
2. 4. 1.1 - /BREAK_CHARACTER=character
/NOBREAK_CHARACTER
(Default=/NOBREAK_CHARACTER)
This qualifier sets up a control character which has the same
effect as entering the BREAK command. The character must be a
single letter representing a control character. For example,
if the character is K, <CTRL/K> acts as a BREAK key.
2. 4. 1.2 - /CCITT
/NOCCITT
(Default=/NOCCITT)
If you use this qualifier and do not specify a DTE address you
may only use the /LOG, /PARAMETER, /VMS_MODE, /PROFILE,
/STATISTICS and /DEFAULT_ESCAPE_CHARACTER qualifiers. PAD will
accept only CCITT commands and an A command is used to make the
call.
If you specify a DTE address, you may use any of the qualifiers.
The PAD will make the call as requested and then enter CCITT
mode.
2. 4. 1.3 - /CLOSED_USER_GROUP[=string]
/NOCLOSED_USER_GROUP
(Default=/NOCLOSED_USER_GROUP)
If this qualifier is present with a value, the value refers to
the name of the closed user group, and the parameter is the
usual DTE address.
When this qualifier is without a value, the DTE address parameter
is assumed to be the name of a bilateral closed user group.
2. 4. 1.4 - /DEFAULT_ESCAPE_CHARACTER=character
/NODEFAULT_ESCAPE_CHARACTER
(Default=/DEFAULT_ESCAPE_CHARACTER=P)
This qualifier changes the control character you type to go into
PAD command mode.
Use this qualifier when accessing a PAD from a console terminal
(or on some other networking product) which interprets <CTRL/P>.
Do not enter <CTRL/P> from a console terminal unless you have set
the terminal to LOCAL DISABLE with the keyswitch. The keyswitch
is on the front of the system that you are using.
If you specify /NODEFAULT_ESCAPE_CHARACTER, you go into PAD
command mode by typing multiple <CTRL/Y>s ( or the host must set
parameter 1 to a value greater than 1 ).
2. 4. 1.5 - /FACILITIES=(number-list)
/NOFACILITIES
(Default=/NOFACILITIES)
This qualifier specifies a list of numbers, in the range 0 to
255, which are in the 'local facilities field' in the NCB (refer
to the X.25 Programming Reference manual for details of the NCB).
This list specifies some local facility not covered by the X.25
software. This field is not checked so the network may reject
the call if you request an invalid facility.
2. 4. 1.6 - /FAST_SELECT
/NOFAST_SELECT
(Default=/NOFAST_SELECT)
This qualifier makes the call with fast select requested.
2. 4. 1.7 - /LOCAL_DTE=string
/NOLOCAL_DTE
(Default=/NOLOCAL_DTE)
The digit string specifies the local DTE address to use for the
outgoing call. This qualifier is not valid if you are using
X.25 Access.
2. 4. 1.8 - /LOG[=file]
/NOLOG
(Default=/NOLOG)
This qualifier sets up a log file which logs copies of all the
data sent and received by the user.
This file is by default PSIPAD.LOG and is in the user's default
directory.
You can set the log file type in the PSI$PADLOG logical name to
either NETWORK or TERMINAL (the default). NETWORK captures data
on the network side of the host-based PAD, TERMINAL captures data
as it appears on your terminal.
Using the /LOG qualifier is the same as using the SET LOG
command which assumes the default /STAMP=SENSE. The /STAMP
qualifier has no effect on the TERMINAL log file.
2. 4. 1.9 - /PACKET_SIZE=number
/NOPACKET_SIZE
(Default=/NOPACKET_SIZE)
Use this qualifier to request the specified packetsize in the
call packet. Otherwise, the network default is used. The
packetsize should be between 16 and 1024 and must be a power of
2. If you request a packetsize larger than the one configured,
X.25 will use the largest size configured.
2. 4. 1.10 - /PARAMETERS=(parameter-list)
/NOPARAMETERS
(Default=/NOPARAMETERS)
The parameter-list consists of compulsory keywords and optional
values such as TIMEOUT=10, NOWRAP and DELETE. This qualifier is
the same as issuing a SET PARAMETER parameter-list command.
X.25 reads the parameter-list before you make your call.
2. 4. 1.11 - /PROFILE=(profile-list)
/NOPROFILE
(Default=/NOPROFILE)
This qualifier is a list of profiles. It is the same as issuing
several "SET PROFILE profile-name" commands, one for each profile
name in the list.
2. 4. 1.12 - /PROTOCOL_IDENTIFIER=string
/NOPROTOCOL_IDENTIFIER
(Default=/PROTOCOL_IDENTIFIER="01")
Use this qualifier to put a non-standard X.29 protocol identifier
string into the 'protocol identifier' field of the call. The
string is interpreted as a series of hexadecimal digits which
fill the first 4 bytes of user data in the call packet. Valid
values for this string are set up by the X.29 protocol.
2. 4. 1.13 - /REVERSE_CHARGING
/NOREVERSE_CHARGING
(Default=/NOREVERSE_CHARGING)
Use this qualifier to request reverse charging in the call
packet.
2. 4. 1.14 - /SUBADDRESS=string
/NOSUBADDRESS
(Default=/NOSUBADDRESS)
If you use this qualifier, the digit string you specify is a
local subaddress in the outgoing call.
2. 4. 1.15 - /STATISTICS
/NOSTATISTICS
(Default=/STATISTICS)
This qualifier displays the duration of the PAD session at the
end of the call.
2. 4. 1.16 - /THRUPUT_CLASS=number
/NOTHRUPUT_CLASS
(Default=/NOTHRUPUT_CLASS)
Use this qualifier to request the specified throughput class in
the call packet.
2. 4. 1.17 - /USER_DATA=string
/NOUSER_DATA
(Default=/NOUSER_DATA)
Use this qualifier to specify a string of user data that is sent
to the remote DTE when the call is established. The maximum size
of the string is 12 characters, unless /FAST_SELECT has been
specified, in which case it is 124 characters.
2. 4. 1.18 - /VMS_MODE
/NOVMS_MODE
(Default=/NOVMS_MODE)
This qualifier causes the PAD to enter VMS mode.
This optimizes communication with the remote DTE if the system is
VMS V4.0 or later. Do not use this qualifier unless you are
connected to a VAX/VMS V4.0 or later system.
2. 4. 1.19 - /WINDOW_SIZE=number
/NOWINDOW_SIZE
(Default=/NOWINDOW_SIZE)
Use this qualifier to request the specified windowsize in the
range of 1-127 in the call packet. Otherwise, the network
default is used. If you request a windowsize larger than the one
configured, X.25 will use the largest size configured.
