To do this, you need to use the command 'setserial /dev/ttyS0 uart none'
(for COM1).  This releases the kernel's control of the serial port.  You
can add a line to your modprobe.conf that looks like this to do is
automatically:

alias char-major-61 lirc_serial
install lirc_serial /usr/bin/setserial /dev/ttyS0 uart none;
/sbin/modprobe --ignore-install lirc_serial

That command is actually two lines, the second one is probably wrapped
in the e-mail.
