Okay it was 2.4.3 when it went in

Fix sysvinit. Oh and all getty programs etc - everything that mucks around with termios.
Alternatively revert the change to drivers/char/serial.c

Oh *ahem* I just read the entire thread again and I remembered it wrong. It's not the CREAD handling perse, it's something else that has changed that caused this, but it appears that a solution hasn't been found yet. Except for fixing all user-space programs. Sysvinit, agetty, busybox etc etc
Okay so ignore my earlier comments. Sorry.
Mike.
