NAME

     ntalk - talk to another user

SYNOPSIS

     ntalk person [ ttyname ]

DESCRIPTION

     Ntalk 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
     person is just the person's login name.  If you wish to talk
     to a user on another  host,  then  person  is  of  the  form
     user@host.

     If you want to talk to a user who is  logged  in  more  than
     once,  the  ttyname  argument  may  be  used to indicate the
     appropriate terminal name, where  ttyname  is  of  the  form
     ``ttyXX''.

     When first called, ntalk sends the message

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

          ntalk  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;  ntalk
     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
     mesg  command.   At  the outset talking is allowed.  Certain
     commands, in particular nroff and pr, disallow  messages  in
     order to prevent messy output.

FILES

     /etc/hosts     to find the recipient's machine
     /etc/utmp      to find the recipient's tty

BUGS

     The version of ntalk(1) released with 4.3BSD uses a protocol
     that  is  incompatible with the protocol used in the version
     released with 4.2BSD.
