4# Change some defaults for serial devices.
5# Standard defaults are:
6#	dtrwait 300 drainwait 0
7#	initial cflag from <sys/ttydefaults.h> = cread cs8 hupcl
8#	initial iflag, lflag and oflag all 0
9#	speed 9600
10#	special chars from <sys/ttydefaults.h>
11#	nothing locked
12# except for serial consoles the initial iflag, lflag and oflag are from
13# <sys/ttydefaults.h> and clocal is locked on.
