Please can anyone explain the magic invocation that's needed to tell Linux to ignore a serial port? I want my Slack installation (kernel 2.4.22) to ignore /dev/ttyS0 and pretend that it doesn't exist. I'm sure that I've seen it written down somewhere - but that might have been to do with ignoring parallel ports? I've tried 'setserial /dev/ttyS0 uart none', which the man page suggests might do the trick, but it doesn't.
Any ideas, please, anyone?

Do you have a getty process running on ttys0? If so, it's defined in /etc/inittab. My distribution (SuSE8.x) has the following line:
#S0:12345:respawn:/sbin/agetty -L 9600 ttys0 vt102
which as you see is commented out. The port is free for whatever use is required of it.

1. don't compile the serial driver into the kernel and don't load it.
OR
2. figure out from http://www.freenix.fr/unix/linux/HOWTO-vo/Serial-HOWTO-10.html#sets_boot_tim... how to feed the driver a useless harmless set of irq and io addresses. I can't.
