serial revision 4982 
1# Change some defauls for serial devices.
2# Standard defaults are:
3#	dtrwait 300
4#	initial cflag from <sys/ttydefaults.h> = cread cs8 hupcl
5#	initial iflag, lflag and oflag all 0
6#	speed 9600
7#	special chars from <sys/ttydefaults.h>
8#	nothing locked
9# except for serial consoles the initial iflag, lflag and oflag are from
10# <sys/ttydefaults.h> and clocal is locked on.
