This is a piece of mipdown.c:

struct	sgttyb	lkterm;

termst()

{
	if(ioctl(f3,TIOCEXCL)==0 &&
	   ioctl(f4,TIOCEXCL)==0){
	    lkterm.sg_ispeed	= bdrate;
	    lkterm.sg_ospeed	= bdrate;
	    lkterm.sg_erase	= ERASECH;
	    lkterm.sg_kill	= KILLCH;
	    lkterm.sg_flags	= FLAG;
	    if(ioctl(f3,TIOCSETP,&lkterm)!=0 ||
	       ioctl(f4,TIOCSETP,&lkterm)!=0){
		error("terminalsettings can not be
changed",-1,"\n");
		finish(-1);
	    }
	}
	else{
	    error("device is busy",-1,"\n");
	    finish(-1);
	}
}

finish(a)

int	a;
{
	ioctl(f3,TIOCNXCL);
	ioctl(f4,TIOCNXCL);
	exit(a);
}


And these are the errors I get:

mipdown.c: In function `termst':
mipdown.c:974: `TIOCEXCL' undeclared (first use in
this function)
mipdown.c:974: (Each undeclared identifier is reported
only once
mipdown.c:974: for each function it appears in.)
mipdown.c:976: invalid use of undefined type `struct
sgttyb'
mipdown.c:977: invalid use of undefined type `struct
sgttyb'
mipdown.c:978: invalid use of undefined type `struct
sgttyb'
mipdown.c:979: invalid use of undefined type `struct
sgttyb'
mipdown.c:980: invalid use of undefined type `struct
sgttyb'
mipdown.c:981: `TIOCSETP' undeclared (first use in
this function)
mipdown.c: In function `finish':
mipdown.c:1019: `TIOCNXCL' undeclared (first use in
this function)
mipdown.c: At top level:
mipdown.c:70: storage size of `lkterm' isn't known

When I change the struct sgtty into termios I get the
following errors:

mipdown.c: In function `termst':
mipdown.c:974: `TIOCEXCL' undeclared (first use in
this function)
mipdown.c:974: (Each undeclared identifier is reported
only once
mipdown.c:974: for each function it appears in.)
mipdown.c:976: structure has no member named

mipdown.c:977: structure has no member named
`sg_ospeed'
mipdown.c:978: structure has no member named
`sg_erase'
mipdown.c:979: structure has no member named `sg_kill'
mipdown.c:980: structure has no member named
`sg_flags'
mipdown.c:981: `TIOCSETP' undeclared (first use in
this function)
mipdown.c: In function `finish':
mipdown.c:1019: `TIOCNXCL' undeclared (first use in
this function)

Can anybody tell me what to change in order to get
this working?
