I think it's the `ty' capability. See printcap(5). I use LPRng, a replacement lpr daemon, which uses a different syntax for specifying serial setup, so I can't give you specifics here. > Both forms are 'accepted' but don't actually change the baud rate. > > I've tried moving the rc.serial file to stop 'locking' style stty commands > on > the /dev/cuala0 locking device at boot time .

You **must** modify the intial device, not the standard device. When you close the standard device, it resets the settings to the initial device's settings. So make sure you're manipulating the /dev/cuaia? devices if you're goign to play with stty. I'd recommend looking at your printing system first and make sure it isn't set up to handle this already. Serial printers used to be very common, so most printing software should handle it OK.
