System: NetBSD ed209 1.0_BETA NetBSD 1.0_BETA (ED209) #0: Sat Aug 20 03:10:19 MET DST 1994 thomas@ed209:/usr/src/sys/arch/i386/compile/ED209 i386

Machine: i386
>Description:
	Every time I start a program (in this case gdb) that uses the sgtty
	instead of the termios terminal interface my terminal settings get
	mangled, i.e. -istrip, cs8, -parenb is changed to istrip, cs7, parenb.
	I've fixed this for gdb by letting it use termios.
>How-To-Repeat:
The program hello that is controlled by gdb below is just the usual
printf("hello world\n"), i.e. it doesn't do anything with the terminal
settings.
