ttydefs(4)                       File Formats                       ttydefs(4)



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 adminis-
                       trator 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 character 'A,' auto-
                       baud will  be enabled. Otherwise, autobaud will be dis-
                       abled. 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 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.
