ADVISE command

Links your terminal with another user's terminal so that you can  give
commands  to  that user's job.  The advisee can still give commands to
his job.


Format

     @ADVISE (USER) argument

     where:

     argument            is either a user name or terminal line
                         number.


Characteristics

     Input to Other Job

     For as long as the ADVISE command is in effect, the commands  you
     give affect the advisee's job instead of your own.

     Ending Advice

     To end an advising link that you have formed  between  terminals,
     you  must  type  CTRL/E.   This  CTRL/E  is  not echoed on either
     terminal.

     Refused Advice

     Ordinarily, you cannot advise a job unless its terminal is set to
     receive   advice.    However,  if  you  have  WHEEL  or  OPERATOR
     capabilities enabled, you can ADVISE any job, providing the  user
     has not given the TERMINAL INHIBIT command.

     Special ADVISE Commands

     Once you are advising another job, you can give special  commands
     to  send  comments  or  control  characters,  or  to  relink to a
     terminal that has broken links with yours.  These commands are:

          CTRL/E         End an ADVISE link

          CTRL/~ +       Restart an ADVISE link after a BREAK command
                         is typed at the advised terminal.

          CTRL/~ (       Start a comment (or use the REMARK command).

          CTRL/~ )       End a comment (or use the REMARK command).

          CTRL/~ ?       Display the list of ADVISE control
                         characters.

          CTRL/~<CHAR>   Send CTRL/CHAR.

                         Note that the tilde character  (~)  can  have
                         different   meanings  with  various  terminal
                         models.  Consult your terminal's  manual  for
                         the character equivalent to 36 octal in ASCII
                         code.


Special Cases

     Advisee Has More Than One Job

     If more than one job  is  logged  in  under  the  user  name  you
     specify,  the  system  gives  you  a list of that user's terminal
     numbers and associated programs to choose from, then prints  TTY:
     to  prompt  your  response.   Type your choice of terminal number
     after the prompt.

     Advising a Pseudoterminal (PTY:)

     If you try to advise a PTY: the system informs you  of  this  and
     asks you to confirm with a carriage return.


Restrictions

     Compatible Terminals

     Unless the terminals involved in an advising link have compatible
     characteristics  (such  as terminal width, ability to handle tabs
     and  lowercase  letters),  some  information  can  be   lost   or
     overprinted.   To  avoid  this problem, the user of the faster or
     more   capable   terminal   should    adjust    his    terminal's
     characteristics, if possible before the ADVISE command is given.

     Detached Jobs

     You cannot advise detached jobs.


Warning

     Talking Between a VT100 and a VT52

     If links between VT100 and VT52 terminals are  established  using
     an  ADVISE  (or  TALK)  command, the VT52 may function improperly
     during or after the linked interval (for  example,  by  requiring
     frequent  CTRL/Q  commands  to  print  multiple lines of output).
     Turning the terminal off and then  on  again  (after  the  linked
     interval) will correct this problem.


Effect on Terminal

     The  ADVISE  command  leaves  your  terminal  at  the   advisee's
     terminal's command level, controlling his job.
