# dtrwait 300 drainwait 0
# initial cflag from <sys/ttydefaults.h> = cread cs8 hupcl
# initial iflag, lflag and oflag all 0
# speed 9600
# special chars from <sys/ttydefaults.h>
# nothing locked
# except for serial consoles the initial iflag, lflag and oflag are from
# <sys/ttydefaults.h> and clocal is locked on.
