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 admin‐
istrator 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.
