Connects your system to a remote system through an outgoing
terminal line.
You must have an account on the remote system in order to log in
to that system after the connection is made.
You must also have the ability to assign a channel to the
terminal port specified. Your system manager can set the device
protection on the terminal port to allow you access.
Format
SET HOST/DTE terminal-name
| 1 - Parameter |
terminal-name
Specifies the name of an outgoing terminal line, which connects
your system directly to another system or modem.
| 2 - Qualifiers |
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, except C, M, Q, S, Y, or the left bracket ([). You cannot
select a character currently defined as either the command
character (see the description of the /COMMAND=command-character
qualifier) or the escape character (see the description of the
/ESCAPE=escape-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 (]).
2.2 - /COMMAND
/COMMAND=command-character
Selects the command character. Use the command character to
access DTE command mode by pressing Ctrl/command-character.
The command character can be any ASCII character between @ and z,
except C, M, Q, S, Y, or the left bracket ([). You cannot select
a character currently defined as either the break character (see
the description of the /BREAK=break-character qualifier) or the
escape character (see the description of the /ESCAPE=escape-
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 - /DIAL
/DIAL=(NUMBER:number[,MODEM_TYPE:modem-type])
Allows a modem attached to the outgoing terminal line to be
autodialed using the autodial protocol of that modem. The
NUMBER keyword is the telephone number to be autodialed and is
a required parameter.
Before you dial a new number, you must log out of the current
remote system.
On Alpha, the MODEM_TYPE keyword defaults to DMCL (any modem that
uses the DEC Modem Command Language).
On VAX, the MODEM_TYPE keyword is optional. It can be used to
specify any of the following modem types:
o DMCL (any modem that uses the DEC Modem Command Language)
o DF03 (default)
o DF112
Each modem type requires a specific modem dialer code. Check with
your system manager to see which modem dialer codes are installed
on your system.
In addition, the MODEM_TYPE keyword can be used to specify
a modem type other than DF03, DF112, or DMCL. A template is
provided for users interested in supporting other modems with
autodial capabilities (see SYS$EXAMPLES:DTE_DF03.MAR).
2.4 - /ECHO
/ECHO
/NOECHO (default)
Determines whether the terminal input is echoed by your local
system. By default, all echoing is performed by the remote
system.
2.5 - /EIGHT_BIT
/EIGHT_BIT (default)
/NOEIGHT_BIT
Determines whether the outgoing terminal line supports 8-bit or
7-bit characters. By default, 8-bit characters are supported. If
you specify /NOEIGHT_BIT, then 7-bit characters are supported.
2.6 - /ERROR_ACTION
/ERROR_ACTION=CONTINUE (default)
/ERROR_ACTION=EXIT
Specifies the error action by using the EXIT or the CONTINUE
keyword.
When an error is detected on the outgoing terminal line, the
error is reported to the local system and an error message is
displayed on your terminal.
If the error action is CONTINUE, then communication with the
remote system continues uninterrupted.
If the error action is EXIT, then the local system immediately
exits from the remote system.
2.7 - /ESCAPE
/ESCAPE=escape-character
Selects the escape character. You can use the escape character to
exit from DTEPAD by pressing Ctrl/ escape-character.
The escape character can be any ASCII character between @ and z,
except C, M, Q, S, Y, or the left bracket ([). 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).
By default, the escape character is a backslash (\).
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 (`).
2.8 - /FLOW_CONTROL
/FLOW_CONTROL (default)
/NOFLOW_CONTROL
Determines whether XON/XOFF flow control is enabled. By default,
flow control is enabled.
XON/XOFF flow control is a means of preventing data-overrun
errors. Incoming data is stored in receive buffers; when these
buffers are full, a signal is sent to the remote system to stop
transmission. Once there is sufficient space in the receive
buffers, another message is sent to restart transmission.
You should disable XON/XOFF flow control when the remote system
has no XON/XOFF flow control.
2.9 - /INIT
/INIT[=filespec] (default)
/NOINIT
Sets the configurable characteristics of DTEPAD according to
values contained in the specified initialization file.
If you use qualifiers in the command line to define the values of
any of the configurable characteristics, these will supersede the
values contained in the initialization file.
By default, DTEPAD tries to translate the logical name DTEPAD$INI
in order to find the appropriate initialization file. If you
use the /INIT qualifier and omit the file specification, DTEPAD
translates the logical name DTEPAD$INI and finds the appropriate
file. If DTEPAD$INI is not defined, then DTEPAD uses /NOINIT as
the default.
An initialization file can contain any combination of any of the
following DTE commands:
o SAVE
o SEND BREAK
o SET DTE
o SPAWN
The following is an example of an initialization file:
SET DTE/MAX_BUFFERS=150
SET DTE/READ_DELAY=100
SEND BREAK
2.10 - /LOG
/LOG[=filespec]
/NOLOG (default)
Controls whether a log file of the session is kept.
If you use the /LOG qualifier and omit the file specification,
then the log information is written to the file DTEPAD.LOG.
When used to log a modem session, the log file contains any noise
that occurred on the phone line. For example, typing a file in
order to get it recorded in the log file could result in noise
being recorded along with the file data. Therefore, the use of a
log file is not recommended for the purpose of file transfers.
Compaq recommends that you use asynchronous DECnet to transfer
files.
2.11 - /MAX_BUFFERS
/MAX_BUFFERS=number-buffers
Specifies the maximum number of receive buffers. Receive buffers
are buffers used to receive incoming data from the modem port.
They are allocated as they are required.
By default, the maximum number of receive buffers is 100. The
minimum number you can specify is 20.
2.12 - /PARITY
/PARITY=NONE (default)
/PARITY=ODD
/PARITY=EVEN
Selects parity on the outgoing terminal line.
2.13 - /READ_DELAY
/READ_DELAY=delay
Specifies the modem port read delay in milliseconds. The modem
port read delay is the time interval during which data in the
modem port is transferred into receive buffers at the terminal.
By default, the modem port read delay is 50 milliseconds. This is
also the minimum value.
A long modem port read delay slows the rate at which data is
displayed at your terminal, and also increases the risk of data-
overrun errors; however, a longer read delay requires less CPU
overhead.
2.14 - /SPEED
/SPEED=(output-rate,input-rate)
Sets the baud rate at which the terminal receives and transmits
data. If the input and output rates are the same, specify the
qualifier as /SPEED=rate.
Not all terminals support different input and output baud rates.
For specific information on baud rates for your terminal, consult
the manual for that terminal.
The default transmission rates are installation dependent.
The valid baud rates are as follows:
50 150 1800 4800 38400
75 300 2000 7200 57600
110 600 2400 9600 76800
134 1200 3600 19200 115200
If you select an invalid or unsupported speed, then the terminal
line speed will remain set at its previous value.
| 3 - Examples |
1.$ SET HOST/DTE TTA2:/DIAL=NUMBER:5551234
Username: SMITH
Password:
This command connects the user terminal to the outgoing
terminal line TTA2:, which is attached to a modem (type DF03
by default) set to autodial the phone number 555-1234. The
remote processor then prompts for user name and password. Use
the normal login procedure to log in to the remote system.
2.$ SET HOST/DTE/DIAL=(NUMBER:5551234#,MODEM_TYPE:DF112) TTA2:
Username: SMITH
Password:
This command accomplishes the same thing as in the first
example, except that it uses the DF112 modem. The number sign
(#) is required to activate the autodialer in the DF112.
3.$ SET HOST/DTE/NOEIGHTBIT TTA2
This command sets the outgoing terminal port, TTA2, to support
7-bit characters.
4.$ SET HOST/DTE/NOFLOW_CONTROL TTA2
This command disables the XON/XOFF flow control.
5.$ SET HOST/DTE/ERROR_ACTION=EXIT TTA2
This command sets the error action to EXIT.
6.$ SET HOST/DTE/MAX_BUFFERS=150 TTA2
This command sets the maximum number of receive buffers to 150.
7.$ SET HOST/DTE/ESCAPE=E TTA2
This command defines the letter E as the escape character. Note
that DTEPAD is not case sensitive.
8.$ SET HOST/DTE/LOG TTA2
This command enables logging of the session. Since no log
file is specified, the log is written to the default log file,
DTEPAD.LOG.
9.$ SET HOST/DTE/INIT=MYFILE.INI TTA2
This command uses the initialization file MYFILE.INI.
10$ <Ctrl/@>
DTEPAD>
