     _\bT_\ba_\bl_\bk is a visual communication program which copies lines
     from your terminal to that of another user.

     If you wish to talk to someone on your own machine, then
     _\bp_\be_\br_\bs_\bo_\bn is just the person's login name.  If you wish to talk
     to a user on another host, then _\bp_\be_\br_\bs_\bo_\bn is of the form
     _\bu_\bs_\be_\br@_\bh_\bo_\bs_\bt.

     If you want to talk to a user who is logged in more than
     once, the _\bt_\bt_\by_\bn_\ba_\bm_\be argument may be used to indicate the
     appropriate terminal name, where _\bt_\bt_\by_\bn_\ba_\bm_\be is of the form
     ``ttyXX''.

     When first called, _\bt_\ba_\bl_\bk sends the message

          Message from TalkDaemon@his_machine...
          talk: connection requested by your_name@your_machine.
          talk: respond with: talk your_name@your_machine

     to the user you wish to talk to. At this point, the reci-
     pient of the message should reply by typing

          talk  your_name@your_machine

     It doesn't matter from which machine the recipient replies,
     as long as his login-name is the same.  Once communication
     is established, the two parties may type simultaneously,
     with their output appearing in separate windows.  Typing
     control L (^L) will cause the screen to be reprinted, while
     your erase, kill, and word kill characters will behave nor-
     mally.  To exit, just type your interrupt character; _\bt_\ba_\bl_\bk
     then moves the cursor to the bottom of the screen and
     restores the terminal to its previous state.

     Permission to talk may be denied or granted by use of the
     _\bm_\be_\bs_\bg command.  At the outset talking is allowed.  Certain
     commands, in particular _\bn_\br_\bo_\bf_\bf and _\bp_\br, disallow messages in
     order to prevent messy output.

     The version of _\bt_\ba_\bl_\bk(1) released with 4.3BSD uses a protocol
     that is incompatible with the protocol used in the version
     released with 4.2BSD.
