1.1 deraadt 54: .Bl -tag -width ttyname
1.14 millert 55: .It Fl H
56: Don't escape characters with the high big set.
57: This may be useful for certain character sets, but could cause erratic
58: behaviour on some terminals.
59: .It Fl s
60: Use smooth scrolling in the
61: .Nm
62: window.
63: The default is to clear the next two rows and jump from the bottom of

1.1 deraadt 65: .It Ar person
66: If you wish to talk to someone on your own machine, then
67: .Ar person
1.10 aaron 68: is just the person's login name.
69: If you wish to talk to a user on another host, then
1.1 deraadt 70: .Ar person
71: is of the form
72: .Ql user@host .
73: .It Ar ttyname
74: If you wish to talk to a user who is logged in more than once, the
75: .Ar ttyname
76: argument may be used to indicate the appropriate terminal

79: is of the form

1.1 deraadt 95: .Pp
1.15 ! deraadt 96: .Dl $ talk \ your_name@your_machine
1.1 deraadt 97: .Pp
98: It doesn't matter from which machine the recipient replies, as
1.10 aaron 99: long as the login name is the same.
100: If the machine is not the one to which
1.3 pjanzen 101: the talk request was sent, it is noted on the screen.
102: Once communication is established,
1.1 deraadt 103: the two parties may type simultaneously, with their output appearing
1.10 aaron 104: in separate windows.
105: Typing control-L
106: .Pq Ql ^L
1.1 deraadt 107: will cause the screen to
1.12 aaron 108: be reprinted, while the erase, kill, and word kill characters will
1.10 aaron 109: behave normally.
1.12 aaron 110: To exit, just type the interrupt character;
1.10 aaron 111: .Nm
1.1 deraadt 112: then moves the cursor to the bottom of the screen and restores the
113: terminal to its previous state.
114: .Pp
115: Permission to talk may be denied or granted by use of the
116: .Xr mesg 1
