NAME
     ttydefs - file contains terminal line  settings  information
     for ttymon

DESCRIPTION
     /etc/ttydefs is an administrative file that contains records
     divided into fields by colons (":").   This information used
     by ttymon to set up the speed and terminal  settings  for  a
     TTY port.


     The ttydefs file contains the following fields:

     ttylabel         The string ttymon tries  to  match  against
                      the  TTY  port's ttylabel field in the port
                      monitor  administrative  file.   It   often
                      describes  the  speed at which the terminal
                      is supposed to run, for example, 1200.


     initial-flags    Contains the initial   termio(7I)  settings
                      to  which  the  terminal  is to be set. For
                      example, the system administrator  will  be
                      able  to specify what the default erase and
                      kill characters will be. initial-flags must
                      be  specified  in  the syntax recognized by
                      the stty command.


     final-flags      final-flags must be specified in  the  same
                      format  as initial-flags. ttymon sets these
                      final settings after a  connection  request
                      has  been  made  and  immediately  prior to
                      invoking a port's service.


     autobaud         If the autobaud field contains the  charac-
                      ter  'A,' autobaud will  be enabled. Other-
                      wise, autobaud  will  be  disabled.  ttymon
                      determines  what  line speed to set the TTY
                      port to by analyzing the  carriage  returns
                      entered. If autobaud has been disabled, the
                      hunt sequence is used for baud rate  deter-
                      mination.


     nextlabel        If the user indicates that the current ter-
                      minal setting is not appropriate by sending
                      a BREAK, ttymon searchs for a ttydefs entry
                      whose ttylabel field matches  the nextlabel
                      field. If a match  is  found,  ttymon  uses
                      that  field as its ttylabel field. A series

                      of speeds is often linked together in  this
                      way   into  a  closed  set  called  a  hunt
                      sequence. For example, 4800 may  be  linked
                      to  1200,  which in turn is linked to 2400,
                      which is finally linked to 4800.
