Ensure that your io ports (which appear in unix as normal files)
have appropriate protections:

	sudo chmod 777 /dev/ttyS0 /dev/ttyS1

(that makes them completely unprotected, of course.  Better to
put them in a group and change the group permissions, but that
becomes more complicated.)  (Some unix utilities seem to change
the port protections for reasons I've never tracked down, so it
can be necessary to repeat this periodically (or track it down.)
For instance, reboots here seem to do some UUCP initialization
that results in UUCP owning /dev/ttyS0, even though there is no
UUCP actually running...)
