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 administra-
           tive 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 com-
           mand.

     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  character  'A,'
           autobaud will  be enabled. Otherwise, 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 determination.

     nextlabel
           If the user indicates that the current  terminal  set-
           ting  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.
