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  rec-
			ognized 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,' 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 dis-
			abled, 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  tty-
			defs  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.
