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 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 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.
