        !            47: .Nm Talk
        !            48: is a visual communication program which copies lines from your

        !            55: .Ar person
        !            56: is just the person's login name.  If you wish to talk to a user on
        !            57: another host, then
        !            58: .Ar person
        !            59: is of the form
        !            60: .Ql user@host .
        !            61: .It Ar ttyname
        !            62: If you wish to talk to a user who is logged in more than once, the
        !            63: .Ar ttyname
        !            64: argument may be used to indicate the appropriate terminal
        !            65: name, where
        !            66: .Ar ttyname
        !            67: is of the form

        !            84: .Pp
        !            85: It doesn't matter from which machine the recipient replies, as
        !            86: long as his login-name is the same.  Once communication is established,
        !            87: the two parties may type simultaneously, with their output appearing
        !            88: in separate windows.  Typing control-L
        !            89: .Ql ^L
        !            90: will cause the screen to
        !            91: be reprinted, while your erase, kill, and word kill characters will
        !            92: behave normally.  To exit, just type your interrupt character;
        !            93: .Nm talk
        !            94: then moves the cursor to the bottom of the screen and restores the
