1.1 deraadt 42: .Ar person
43: .Op Ar ttyname
44: .Sh DESCRIPTION
1.10 aaron 45: .Nm
1.1 deraadt 46: is a visual communication program which copies lines from your
47: terminal to that of another user.
48: .Pp
1.8 aaron 49: The command arguments are as follows:
1.1 deraadt 50: .Bl -tag -width ttyname
1.14 millert 51: .It Fl H
1.16 fgsch 52: Don't escape characters with the high bit set.
1.18 jmc 53: This may be useful for certain character sets, but could cause erratic
1.14 millert 54: behaviour on some terminals.
55: .It Fl s
56: Use smooth scrolling in the
57: .Nm
58: window.
59: The default is to clear the next two rows and jump from the bottom of
60: the window to the top.
1.1 deraadt 61: .It Ar person
62: If you wish to talk to someone on your own machine, then
63: .Ar person
1.10 aaron 64: is just the person's login name.
65: If you wish to talk to a user on another host, then
1.1 deraadt 66: .Ar person
67: is of the form
68: .Ql user@host .
69: .It Ar ttyname
70: If you wish to talk to a user who is logged in more than once, the
71: .Ar ttyname
72: argument may be used to indicate the appropriate terminal
73: name, where
74: .Ar ttyname
75: is of the form
76: .Ql ttyXX .

1.1 deraadt 84: talk: connection requested by your_name@your_machine.
85: talk: respond with: talk your_name@your_machine
86: .Ed
87: .Pp
1.11 aaron 88: to the user you wish to talk to.
89: At this point, the recipient of the message should reply by typing
1.1 deraadt 90: .Pp
1.15 deraadt 91: .Dl $ talk \ your_name@your_machine
1.1 deraadt 92: .Pp
93: It doesn't matter from which machine the recipient replies, as
1.10 aaron 94: long as the login name is the same.
95: If the machine is not the one to which
1.3 pjanzen 96: the talk request was sent, it is noted on the screen.
97: Once communication is established,
1.1 deraadt 98: the two parties may type simultaneously, with their output appearing
1.10 aaron 99: in separate windows.
100: Typing control-L
101: .Pq Ql ^L
1.1 deraadt 102: will cause the screen to
1.12 aaron 103: be reprinted, while the erase, kill, and word kill characters will
1.10 aaron 104: behave normally.
1.12 aaron 105: To exit, just type the interrupt character;
1.10 aaron 106: .Nm
1.1 deraadt 107: then moves the cursor to the bottom of the screen and restores the
108: terminal to its previous state.
109: .Pp
110: Permission to talk may be denied or granted by use of the
111: .Xr mesg 1
1.10 aaron 112: command.
113: At the outset talking is allowed.
114: Certain commands, in particular
1.1 deraadt 115: .Xr nroff 1
116: and
117: .Xr pr 1 ,
118: disallow messages in order to
119: prevent messy output.
120: .Sh FILES

122: .It Pa /etc/hosts
123: to find the recipient's machine
