Library /sys$common/syshlp/NCPHELP.HLB  —  CLEAR  LINE
 Use the CLEAR LINE command to remove line parameters (or reset the
 parameters to their default values) from the volatile database on
 the executor node.  For an X25 line, the default value depends on the
 NETWORK parameter in the permanent database.  Use the PURGE LINE
 command to remove line parameters from the permanent database on
 the executor node.

     CLEAR   KNOWN LINES     (parameters...)
             LINE line-id

 All underscores found in parameters must be replaced with spaces
 when parameters are used in NCP commands.

1  –  KNOWN LINES 

 Resets to the default (if any) or removes the parameters for all
 known lines from the volatile database.

2  –  LINE line-id 

 Identifies the specific line whose parameters are to be reset to their
 default values (if any) or removed from the volatile database.

3  –  ALL 

 Removes the specified line or all known lines from the volatile database.
 The line must be in the OFF state before you specify this parameter.

4  –  COUNTER TIMER 

 Resets the logging timer to zero.  This prevents any further line
 counter logging for the indicated line(s).

5  –  DEAD TIMER 

 Applies only to DDCMP lines.  Resets to its default the DEAD TIMER
 parameter in the volatile database.

6  –  DELAY TIMER 

 Applies only to DDCMP lines.  Resets to its default the DELAY TIMER
 parameter in the volatile database.

7  –  ECHO

7.1  –  DATA 

 Applies only to FDDI lines.  Resets to its default the ECHO DATA
 parameter in the volatile database.  Permanent database operations
 cannot be performed on this parameter.

7.2  –  LENGTH 

 Applies only to FDDI lines.  Resets to its default the ECHO LENGTH
 parameter in the volatile database.  Permanent database operations
 cannot be performed on this parameter.

7.3  –  TARGET 

 Applies only to FDDI lines.  Resets to its default the ECHO TARGET
 parameter in the volatile database.  Permanent database operations
 cannot be performed on this parameter.

8  –  HANGUP 

 Applies only to asynchronous DDCMP lines.  Removes from the volatile
 database the HANGUP state of the line.

9  –  INTERFACE 

 Applies only to X25 lines.  Resets the INTERFACE parameter to the
 default value of DTE.

10  –  LINE SPEED 

 Applies only to asynchronous DDCMP lines. Removes from the volatile
 database the Line Speed parameter.

11  –  MAXIMUM RETRANSMITS 

 Applies only to X25 lines.  Resets the maximum number of retransmissions
 of a frame to the default value for the specified line or all known lines
 in the volatile database.

12  –  NETWORK 

 Applies only to X25 lines.  Removes the NETWORK parameter from the
 permanent database.

13  –  NIF TARGET 

 Applies only to FDDI lines.  Resets to its default value the NIF TARGET
 parameter in the volatile database.  Permanent database operations
 cannot be performed on this parameter.

14  –  RECEIVE BUFFERS 

 Applies only to DDCMP lines.  Resets to its default value the RECEIVE
 BUFFERS parameter in the volatile database.

15  –  REQUESTED TRT 

 Applies only to FDDI lines.  Resets to its default value the REQUESTED
 TRT parameter in the volatile database.

16  –  RESTRICTED TOKEN TIMEOUT 

 Applies only to FDDI lines.  Resets to its default value the RESTRICTED
 TOKEN TIMEOUT parameter in the volatile database.

17  –  RING PURGER ENABLE 

 Applies only to FDDI lines.  Resets to its default value the RING PURGER
 ENABLE parameter in the volatile database.

18  –  SCHEDULING TIMER 

 Applies only to DDCMP lines.  Resets to its default value the SCHEDULING
 TIMER parameter in the volatile database.

19  –  SIF

19.1  –  CONFIGURATION TARGET 

 Applies only to FDDI lines.  Resets to its default value the
 SIF CONFIGURATION TARGET parameter in the volatile database.
 Permanent database operations cannot be performed on this parameter.

19.2  –  OPERATION TARGET 

 Applies only to FDDI lines.  Resets to its default value the
 SIF OPERATION TARGET parameter in the volatile database.
 Permanent database operations cannot be performed on this parameter.

20  –  STREAM TIMER 

 Applies only to DDCMP lines.  Resets to its default value the STREAM
 TIMER parameter in the volatile database.

21  –  SWITCH 

 Applies only to asynchronous DDCMP lines.  Removes from the volatile
 database the SWITCH parameter.

22  –  TRANSMIT PIPELINE 

 Applies only to DMR11 lines.  Removes from the volatile database the
 TRANSMIT PIPELINE parameter.

23  –  VALID TRANSMISSION TIME 

 Applies only to FDDI lines.  Resets to its default value the VALID
 TRANSMISSION TIME parameter in the volatile database.

24  –  Examples 

      NCP>CLEAR LINE DMC-0 ALL

          This command removes line DMC-0 from the volatile database.

      NCP>CLEAR KNOWN LINES MAXIMUM RETRANSMITS

          This command resets the maximum number of retransmissions of
          a frame for all known lines in the volatile database.  The
          parameter is reset to its default value.
