Chapter 17
DDU Commands

This chapter provides reference information and examples for each ACMS Device Definition Utility (DDU) command. See Chapter 2 for a general description of DDU.


ADD Command (DDU>)

Authorizes and assigns sign-in characteristics to an ACMS terminal by creating a DDU definition and adding it to the device authorization file (ACMSDDF.DAT).

Format

ADD device-name

Command Qualifiers Default
/[NO]AUTOLOGIN=username From DEFAULT definition
/[NO]CONTROLLED From DEFAULT definition
/PRINTFILE
  • =
    • print-file-spec
    • spooled-device-name
From DEFAULT definition


Privileges Required

None

Parameters

device-name

The name of the device. The device name can be a logical name, a physical device name, or a group device name. Do not include a colon (:) when you specify a device name. See Table 2-1 for a list of the DDU group device names.

Qualifiers

/[NO]AUTOLOGIN=username

The /AUTOLOGIN qualifier enables automatic sign-ins for ACMS-controlled terminals. With automatic sign-in enabled, the user does not need to enter a user name to sign in to ACMS. If a password is required, the user receives the password prompt after pressing [Return]. If a password is not required, the user is signed in to ACMS as soon as [Return] is pressed on the terminal's keyboard.

ACMS places the user name you specify with the /AUTOLOGIN qualifier in the device authorization file and uses that user name each time a user presses [Return]. The user name can contain 1 through 12 characters.

The /AUTOLOGIN qualifier has no effect unless the terminal has the Controlled sign-in characteristic. You can assign a Controlled sign-in characteristic by specifying the /CONTROLLED qualifier.

Disable automatic sign-ins with the /NOAUTOLOGIN qualifier. The default for this qualifier is whatever is defined in the DEFAULT definition. See the description of the DDU DEFAULT command for information on the DEFAULT definition.

/[NO]CONTROLLED

The /CONTROLLED qualifier assigns the Controlled sign-in characteristic to a device. Users at application port terminals with the Controlled sign-in characteristic sign in directly to ACMS. Users at dedicated service port terminals sign in either directly to ACMS or not, depending on the node they connect to at the "Local>" prompt. See Section 2.11 for a description of application ports and dedicated service ports.

The /NOCONTROLLED qualifier assigns the Not Controlled sign-in characteristic to a device. Users at terminals with the Not Controlled characteristic sign in directly to OpenVMS. For access to ACMS, you must enter the ACMS/ENTER command.

When you specify the /CONTROLLED qualifier, you can specify only a physical device name or the group device names TT and LT. See Table 2-1 for a description of the DDU group device names. The default for this qualifier is whatever is defined in the DEFAULT definition. See the description of the DDU DEFAULT command for information on the DEFAULT definition.

Note

The ACMS Terminal Subsystem Controller (TSC) does not support dialup lines as ACMS-controlled terminals. Because the TSC keeps a channel to ACMS-controlled terminals even when the user signs out, the modem does not receive any hangup notification. If you operate a terminal using ACMS over dialup lines, you must first log in to OpenVMS, and then issue the ACMS/ENTER/NORETURN command. The /NORETURN qualifier deletes the OpenVMS process after you enter ACMS.

/PRINTFILE=print-file-spec
/PRINTFILE=spooled-device-name

The /PRINTFILE qualifier assigns the Printfile characteristic to a device. The print response must appear in the form source IFDL file, and a print key must also be defined there. When the user presses the print key, the DECforms panel screens are automatically sent to the print file or spooled device specified after the /PRINTFILE qualifier.

When you specify the /PRINTFILE qualifier, you can specify only a spooled device name or a file name. The default for this qualifier is whatever is defined in the DEFAULT definition.


Notes

DDU writes the definition you are creating to the device authorization file in your current default directory, or to the file pointed to by the EXECUTIVE mode system logical name, ACMSDDF.

New definitions go into effect after you use the ACMS/RESET TERMINALS command, the ACMS/START SYSTEM command, or the ACMS/START TERMINALS command.

For more information about the DDU database authorization file (ACMSDDF.DAT) and the DDU in general, see Chapter 2.


Examples

#1

DDU> ADD TTE6
      

This command creates a device definition for the terminal TTE6, using the sign-in characteristics defined in the DDU DEFAULT definition.

#2

DDU> ADD TTE6 /CONTROLLED/AUTOLOGIN=JUDGE
      

This command creates a device definition with the Controlled and Autologin sign-in characteristics for terminal TTE6. Users at terminal TTE6 sign in directly to ACMS without typing a user name. ACMS places the user name JUDGE in the device definition file and uses that user name whenever a user presses [Return] at terminal TTE6.

#3

DDU> ADD $ALL/NOCONTROLLED
      

This command adds a definition for the group device name $ALL, which authorizes all unauthorized terminals and assigns the terminals the Not Controlled sign-in characteristic.

#4

DDU> ADD LT /NOCONTROLLED
      

This command adds a definition for the group device name LT. The LT device name authorizes all unauthorized LAT terminals and assigns the terminals the Not Controlled sign-in characteristic.


COPY Command (DDU>)

Authorizes a terminal, using the sign-in characteristics from the DDU definition you specify.

Format

COPY source-device-name new-device-name

Command Qualifiers Default
/[NO]AUTOLOGIN=user-name From source definition
/[NO]CONTROLLED From source definition
/PRINTFILE
  • =
    • print-file-spec
    • spooled-device-name
From source definition


Privileges Required

None

Parameters

source-device-name

The device name in the source definition. The source device name can be a logical name, a physical device name, or a group device name. Do not include a colon (:) when you specify a device name. See Table 2-1 for a list of the DDU group device names.

new-device-name

The device name in the definition you are creating. The new device name cannot already exist in the device authorization file. See source-device-name for syntax rules.

Qualifiers

/[NO]AUTOLOGIN=user-name

The /AUTOLOGIN qualifier enables automatic sign-ins for ACMS-controlled terminals. With automatic sign-in enabled, the user does not need to enter a user name to sign in to ACMS. If a password is required, the user receives the password prompt after pressing [Return]. If a password is not required, the user is signed in to ACMS as soon as [Return] is pressed on the terminal's keyboard.

ACMS places the user name you specify with the /AUTOLOGIN qualifier in the device authorization file and uses that user name each time a user presses [Return] at that terminal. A user name can contain 1 through 12 characters.

The /AUTOLOGIN qualifier has no effect unless the terminal has the Controlled sign-in characteristic. Assign a Controlled sign-in characteristic by specifying the /CONTROLLED qualifier. Disable automatic sign-ins with the /NOAUTOLOGIN qualifier. The default for this qualifier is whatever is defined in the definition you are copying.

/[NO]CONTROLLED

The /CONTROLLED qualifier assigns the Controlled sign-in characteristic to a device. Users at application port terminals with the Controlled sign-in characteristic sign in directly to ACMS. Users at dedicated service port terminals sign in either directly to ACMS or not, depending on the node they connect to at the "Local>" prompt. See Section 2.11 for a description of application ports and dedicated service ports.

The /NOCONTROLLED qualifier assigns the Not Controlled sign-in characteristic to a device. Users at terminals with the Not Controlled characteristic log in directly to OpenVMS. For access to ACMS, you must enter the ACMS/ENTER command.

When you use the /CONTROLLED qualifier, you can specify only a physical device name or the group device names TT and LT. See Table 2-1 for a description of the DDU group device names. The default for this qualifier is whatever is defined in the definition you are copying.

Note

The ACMS Terminal Subsystem Controller (TSC) does not support dialup lines as ACMS-controlled terminals. Because the TSC keeps a channel to ACMS-controlled terminals even when the user signs out, the modem does not receive any hangup notification. If you operate a terminal using ACMS over dialup lines, you must first log in to OpenVMS, and then issue the ACMS/ENTER/NORETURN command. The /NORETURN qualifier deletes the OpenVMS process after you enter ACMS.

/PRINTFILE=print-file-spec
/PRINTFILE=spooled-device-name

The /PRINTFILE qualifier assigns the Printfile characteristic to a device. The PRINT response must appear in the form source IFDL file, and a print key must also be defined there. When the user presses the print key, the DECforms panel screens automatically are sent to the print file or spooled device specified after the /PRINTFILE qualifier.

When you specify the /PRINTFILE qualifier, you can specify only a spooled device name or a file name. The default for this qualifier is The default for this qualifier is whatever is defined in the definition you are copying.


Notes

DDU writes the definition you are creating to the device authorization file in your current default directory, or to the file pointed to by the EXECUTIVE mode system logical name, ACMSDDF.

Changes to definitions go into effect after you use one of the following commands:


Example


DDU> COPY TTE1 TTE2
      

This command authorizes terminal TTE2 using the sign-in characteristics defined for terminal TTE1.


DEFAULT Command (DDU>)

Changes information in the DDU DEFAULT definition.

Format

DEFAULT

Command Qualifiers Default
/[NO]AUTOLOGIN=user-name From current DEFAULT definition
/[NO]CONTROLLED From current DEFAULT definition
/PRINTFILE
  • =
    • print-file-spec
    • spooled-device-name
From DEFAULT definition


Privileges Required

None

Qualifiers

/[NO]AUTOLOGIN=user-name

The /AUTOLOGIN qualifier enables automatic sign-ins for ACMS-controlled terminals. With automatic login enabled, the user does not need to enter a user name to sign in to ACMS. If a password is required, the user receives the password prompt after pressing [Return]. If a password is not required, the user is signed in to ACMS as soon as [Return] is pressed on the terminal's keyboard.

ACMS places the user name you specify with the /AUTOLOGIN qualifier in the device authorization file and uses that user name each time a user presses [Return] at that terminal. The user name can contain 1 through 12 characters.

The /AUTOLOGIN qualifier has no effect unless the terminal has the Controlled sign-in characteristic. Assign a Controlled sign-in characteristic by specifying the /CONTROLLED qualifier. Disable automatic sign-ins with the /NOAUTOLOGIN qualifier. The default is whatever sign-in characteristics are currently defined in the DDU DEFAULT definition.

/[NO]CONTROLLED

The /CONTROLLED qualifier assigns the Controlled sign-in characteristic to a device. Users at application port terminals with the Controlled sign-in characteristic sign in directly to ACMS. Users at dedicated service port terminals sign in either directly to ACMS or not, depending on the node they connect to at the "Local>" prompt. See Section 2.11 for a description of application ports and dedicated service ports.

The /NOCONTROLLED qualifier assigns the Not Controlled sign-in characteristic to a device. Users at terminals with the Not Controlled characteristic log in directly to OpenVMS. For access to ACMS, you must enter the ACMS/ENTER command.

When you specify the /CONTROLLED qualifier, you can specify only a physical device name or the group device names TT and LT. See Table 2-1 for a description of the DDU group device names. The default is whatever sign-in characteristics are currently defined in the DDU DEFAULT definition.

If you operate a terminal using ACMS over dialup lines, you must first log in to OpenVMS, and then issue the ACMS/ENTER/NORETURN command. The /NORETURN qualifier deletes the OpenVMS process after you enter ACMS.

/PRINTFILE=print-file-spec
/PRINTFILE=spooled-device-name

The /PRINTFILE qualifier assigns the Printfile characteristic to a device. The PRINT response must appear in the form source IFDL file, and a print key must also be defined there. When the user presses the print key, the DECforms panel screens automatically are sent to the print file or spooled device specified after the /PRINTFILE qualifier.

When you specify the /PRINTFILE qualifier, you can specify only a spooled device name or a file name. The default for this qualifier is whatever is defined in the default definition.


Notes

The ADD command is the only command affected by the characteristics defined in the DDU DEFAULT definition. If you do not specify any qualifiers when you use the ADD command to create a new DDU definition, the definition takes the sign-in characteristics assigned in the DEFAULT definition. You can use qualifiers with the ADD command to override the characteristics defined with the DEFAULT command.

ACMS creates a DEFAULT definition the first time you run DDU, or whenever you create a new device authorization file. By default, the DDU DEFAULT definition created by ACMS has the Not Controlled and No Autologin sign-in characteristics.

Changes to definitions go into effect after you use one of the following commands:


Example


DDU> DEFAULT /NOCONTROLLED
      

This command specifies that the DEFAULT definition has the Not Controlled sign-in characteristic.


EXIT Command (DDU>)

Ends the DDU session and returns you to the DCL prompt.

Format

EXIT


Privileges Required

None

Notes

You can also end a session by pressing [Ctrl/Z]. Pressing [Ctrl/Z] signals the end of the file for data entered from the terminal. EXIT is displayed when you press [Ctrl/Z].

Example


DDU> EXIT
$ 
      

This command causes you to exit from DDU and returns you to DCL.


HELP Command (DDU>)

Displays information about DDU commands and qualifiers.

Format

HELP [ topic [...] ]

Command Qualifier Default
