48: .Sh DESCRIPTION
1.10 aaron 49: .Nm
1.1 deraadt 50: is a visual communication program which copies lines from your
51: terminal to that of another user.
52: .Pp
1.8 aaron 53: The command arguments are as follows:
1.1 deraadt 54: .Bl -tag -width ttyname
55: .It Ar person
56: If you wish to talk to someone on your own machine, then
57: .Ar person
1.10 aaron 58: is just the person's login name.
59: If you wish to talk to a user on another host, then
1.1 deraadt 60: .Ar person
61: is of the form
62: .Ql user@host .
63: .It Ar ttyname
64: If you wish to talk to a user who is logged in more than once, the
65: .Ar ttyname
66: argument may be used to indicate the appropriate terminal
67: name, where
68: .Ar ttyname
69: is of the form
70: .Ql ttyXX .
71: .El
1.13 ! hugh 72: .Pp
! 73: If the
! 74: .Fl H
! 75: argument is given, talk will not escape high characters.
! 76: This may be useful for certain character sets, but could cause erratic
! 77: behaviour on some terminals.
1.1 deraadt 78: .Pp
79: When first called,
1.10 aaron 80: .Nm
1.1 deraadt 81: sends the message
1.10 aaron 82: .Pp
1.1 deraadt 83: .Bd -literal -offset indent -compact
1.5 pjanzen 84: Message from Talk_Daemon@localhost...
1.1 deraadt 85: talk: connection requested by your_name@your_machine.
86: talk: respond with: talk your_name@your_machine
87: .Ed
88: .Pp
1.11 aaron 89: to the user you wish to talk to.
90: At this point, the recipient of the message should reply by typing
1.1 deraadt 91: .Pp
92: .Dl talk \ your_name@your_machine
93: .Pp
94: It doesn't matter from which machine the recipient replies, as
1.10 aaron 95: long as the login name is the same.
96: If the machine is not the one to which
1.3 pjanzen 97: the talk request was sent, it is noted on the screen.
98: Once communication is established,
1.1 deraadt 99: the two parties may type simultaneously, with their output appearing
1.10 aaron 100: in separate windows.
101: Typing control-L
102: .Pq Ql ^L
1.1 deraadt 103: will cause the screen to
1.12 aaron 104: be reprinted, while the erase, kill, and word kill characters will
1.10 aaron 105: behave normally.
1.12 aaron 106: To exit, just type the interrupt character;
1.10 aaron 107: .Nm
1.1 deraadt 108: then moves the cursor to the bottom of the screen and restores the
109: terminal to its previous state.
110: .Pp
111: Permission to talk may be denied or granted by use of the
112: .Xr mesg 1
1.10 aaron 113: command.
114: At the outset talking is allowed.
115: Certain commands, in particular
1.1 deraadt 116: .Xr nroff 1
117: and
118: .Xr pr 1 ,
119: disallow messages in order to
120: prevent messy output.
