  37 .Sh NAME
  38 .Nm talk
  39 .Nd talk to another user
  40 .Sh SYNOPSIS
  41 .Nm talk
  42 .Ar person
  43 .Op Ar ttyname
  44 .Sh DESCRIPTION
  45 .Nm Talk
  46 is a visual communication program which copies lines from your
  47 terminal to that of another user.
  48 .Pp
  49 Options available:
  50 .Bl -tag -width ttyname
  51 .It Ar person
  52 If you wish to talk to someone on your own machine, then
  53 .Ar person
  54 is just the person's login name.  If you wish to talk to a user on
  55 another host, then
  56 .Ar person
  57 is of the form
  58 .Ql user@host .
  59 .It Ar ttyname
  60 If you wish to talk to a user who is logged in more than once, the
  61 .Ar ttyname
  62 argument may be used to indicate the appropriate terminal
  63 name, where
  64 .Ar ttyname
  65 is of the form
  66 .Ql ttyXX .
  67 .El
  68 .Pp
  69 When first called,
  70 .Nm talk
  71 sends the message
  72 .Bd -literal -offset indent -compact
  73 Message from TalkDaemon@his_machine...
  74 talk: connection requested by your_name@your_machine.
  75 talk: respond with: talk your_name@your_machine
  76 .Ed
  77 .Pp
  78 to the user you wish to talk to. At this point, the recipient
  79 of the message should reply by typing
  80 .Pp
  81 .Dl talk \ your_name@your_machine
  82 .Pp
  83 It doesn't matter from which machine the recipient replies, as
  84 long as his login-name is the same.  Once communication is established,
  85 the two parties may type simultaneously, with their output appearing
  86 in separate windows.  Typing control-L
  87 .Ql ^L
  88 will cause the screen to
  89 be reprinted, while your erase, kill, and word kill characters will
  90 behave normally.  To exit, just type your interrupt character;
  91 .Nm talk
  92 then moves the cursor to the bottom of the screen and restores the
  93 terminal to its previous state.
  94 .Pp
  95 Permission to talk may be denied or granted by use of the
  96 .Xr mesg 1
  97 command.  At the outset talking is allowed.  Certain commands, in
  98 particular
  99 .Xr nroff 1
 100 and
 101 .Xr pr 1 ,
 102 disallow messages in order to
 103 prevent messy output.
