Thanks for the tip, Kent, but it want to do it silently because I won't
be there. Also I think you can get a beep without the speaker device
being built into the kernel, but I know you can't play tunes on the
speaker without it.
The script goes like this:
1.
test (secretly) that PC speaker device is accessible by the user
if not privileged, provide instructions for changing permissions
and exit the program
if the user is allowed to write to /dev/speaker, continue with test 2
2.
test for kernel PC speaker support
if unsupported, provide instructions for building it into the kernel
and exit the program
if supported, run the rest of the program as if nothing had been
going on, without mentioning the testing at all
I can do both of these tests OK, but there might be a better way.
The second of the two tests is the one that I think I could improve.
