TOPS-20 Commands Reference Manual

UNATTACH

Disengages another job from its terminal.

Format

@UNATTACH (USER) name (JOB #) number
PASSWORD:password

where:

name	is the user name of the job's owner.
number	is the job number. Default number - the only job, or only job besides your current (attached) job, logged in under the user name you give.
password	is the associated password (not requested if you are currently logged in under the same user name as the job that you are disengaging).

Characteristics

Log-in Not Necessary

You do not have to be logged in to give the UNATTACH command.

Hints

Freeing Hung Terminals

The UNATTACH command is useful for freeing a terminal that, because of program or hardware errors, is no longer under control of the user. The command UNATTACH n can be more effective than LOGOUT n for this purpose.

Effect on Memory and Terminal

The UNATTACH command does not affect memory and leaves your own terminal at TOPS-20 command level. The other job is left in its current state (usually suspended) and the disengaged terminal is left in the state before log-in.

Related Commands

ADVISE	for sending commands to another job
ATTACH	for joining another job to your terminal
DETACH	for disengaging your own job from its terminal

Give a SYSTAT command to find out what jobs you have running. Give the UNATTACH command for two of them (you must specify a job number for the first one so the system will know which one you mean), and check them with another SYSTAT command.

@SYSTAT LATTA
  28    26  EXEC     LATTA
  36*  230  EXEC     LATTA
  40    27  EXEC     LATTA
@UNATTACH LATTA 28
 [Attached to TTY26, confirm]
@UNATTACH LATTA
@SYSTAT LATTA
  28   DET  EXEC     LATTA
  36*  230  EXEC     LATTA
  40   DET  EXEC     LATTA
