User Commands                                          SLEEPER(1)



NAME
     sleeper - acquire a graphics terminal and hang around

SYNOPSIS
     sleeper

DESCRIPTION
     Certain  programs  such as magic(1) can require the use of a
     graphics terminal separate from the terminal used to run the
     program.   If  the  graphics  terminal has an ordinary login
     process running on it, it is necessary  to  run  sleeper  to
     acquire  ownership  of the terminal, set up its modes appro-
     priately, and prevent the login process  from  eating  input
     destined for the CAD tool.

     When sleeper is run, it will print a message of the form:

               tty is:
               /dev/ttyname

     Here, /dev/ttyname is the device name of the graphics termi-
     nal.  This is particularly useful when sleeper is  run  over
     the network, or when using fsleeper(1) or rsleeper(1).

     Sleeper  may be killed by sending it two QUIT signals within
     ten seconds of each other.  This is most easily done by typ-
     ing  two quit characters (usually CTRL-\ or CTRL-SHIFT-L) in
     a row on the graphics terminal.

     For sleeper to work best, there should be an  account  named
     sleeper,  whose  login shell is ~cad/bin/sleeper and with no
     password.  This enables users to log in as the user sleeper,
     and  is  also  necessary  for  the  programs fsleeper(1) and
     rsleeper(1) to work.  (Note that you will  have  to  include
     the  full  pathname  of ~cad/bin/sleeper in /etc/passwd; the
     initial ~cad does not get expanded).
