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
TY port.
The ttydefs file contains the following fields:
ttylabel The string ttymon tries to match against
the TY 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 charac-
ter 'A,' autobaud will be enabled. Other-
wise, autobaud will be disabled. ttymon
determines what line speed to set the TY
port to by analyzing the carriage returns
entered. If autobaud has been disabled, the
hunt sequence is used for baud rate deter-
mination.
nextlabel If the user indicates that the current ter-
minal 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.
