TALK command

The TALK command allows you to  converse  with  other  users  on  your
system by linking terminals.


     @TALK (TO) argument


     argument     is a user name or terminal line number.


     Typing TALK Conversation

          During a TALK session, you must tell the  system  to  regard
          your   conversation  as  comments.   Otherwise,  the  system
          interprets your input as attempts to give EXEC commands  and
          responds  with the message ?Unrecognized command.  To signal
          your input as comments, begin each line with the exclamation
          point  (!)  or semicolon (;) comment character.  Or, if your
          comment is several lines long, use the REMARK command.

     Other Job Not Affected

          As  soon  as  you  give  a  successful  TALK  command,  both
          terminals  begin  printing  both users' input as well as the
          system's responses to that input.  Each job,  however,  will
          receive input from its own terminal only.

     Ending TALK

          To end a conversation link between  terminals,  either  user
          can give the BREAK command.

     Refused TALK

          Terminals can be set to refuse links  with  other  terminals
          with  the  REFUSE LINKS or TERMINAL INHIBIT command.  If you
          attempt to TALK to a user who has refused links from another
          terminal,  the  system rings the bells on both terminals six
          times, and then prints the message, ?Refused, Send  mail  to
          user   instead.   If  the  user  has  refused  all  terminal
          communication with the TERMINAL INHIBIT command, the  system
          does not ring the bell on his terminal.

          If you have Wheel or Operator capabilities enabled, you  can
          TALK to any user who has given the REFUSE LINKS command, but
          not the TERMINAL INHIBIT command.

     Maximum of Four Terminals

          By using TALK commands, you can link up to four terminals at
          once.   For  all  terminals  to share the same display, each
          pair of terminals must establish a link.   For  example,  if
          terminal  A  is  linked  to  B and C, terminals B and C will
          display only A's input.  B and C must establish  a  link  to
          display each other's input.


     Signaling a Linked User

          Once you have established links with another user's terminal
          via  the TALK command, you can get his attention by typing a
          series of CTRL/Gs.  Depending on the  kind  of  terminal  he
          has,   these   will   be  reproduced  as  ringing  bells  or
          high-pitched beeps.  This action can  be  especially  useful
          when   establishing  links  with  the  owner  of  a  display
          terminal,  as  display  terminals  are  silent  in  ordinary

Special Cases

     User Has More Than One Job

          If more than one job is logged in under the  user  name  you
          specify,  the  system  responds  with  a list of that user's
          terminal line numbers and the programs being run.  Type your
          choice  of  terminal  line  number  (if  available,  the one
          running the EXEC) after the TTY:  prompt.

     Talking to a Batch Job or PTYCON Job

          When you link to a PTY  (pseudo-terminal)  to  talk  to  the
          owner  of  a batch job or PTYCON job, the system informs you
          of this with a message, to  which  you  must  reply  with  a
          carriage  return  to confirm the link.  To decline the link,
          give a CTRL/C.  See also Warning, Talking to  a  Batch  Job,


     Talking to a Batch Job

          Use   caution   when    communicating    through    a    PTY
          (pseudo-terminal)  that  is controlling a batch job:  do not
          send a question mark (?) or percent sign (%), because  these
          characters  can be attributed to errors occurring within the
          job.  Also, if an error actually does occur in the batch job
          and  the  batch system's question mark is displaced (by your
          remarks) from the beginning of a line, the  system  may  not
          recognize it as an error.

     Talking Between a VT100 and a VT52

          If links between VT100 and VT52  terminals  are  established
          using  a  TALK  (or  ADVISE)  command, the VT52 may function
          improperly during or after the linked interval (such  as  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.
