TTYS(V)                      2/11/75                      TTYS(V)







NAME

     ttys - typewriter initialization data



DESCRIPTION

     The ttys file is read by  the  init  program  and  specifies

     which typewriter special files are to have a process created

     for them which will allow people to log in.  It consists  of

     lines of 3 characters each.



     The first character is either `0' or `1'; the former  causes

     the  line  to  be  ignored,  the  latter  causes  it  to  be

     effective.  The second character is the  last  character  in

     the  name  of  a  typewriter;  e.g.  x  refers  to  the file

     `/dev/ttyx'.  The third character is used as an argument  to

     the  getty  program,  which performs such tasks as baud-rate

     recognition, reading the login name, and calling login.  For

     normal  lines, the character is `0'; other characters can be

     used, for example, with  hard-wired  terminals  where  speed

     recognition   is   unnecessary   or   which   have   special

     characteristics.  (Getty will  have  to  be  fixed  in  such

     cases.)
