Very old bug, now 99.999999999% eliminated, used to eat the first the 
first paragraph of messages. You can ignore it.

Look in the lattice manual under "Break Handling", there are a couple of
functions one onbreak() sets a pointer for the break handling, and the
more UNIX like signal() call which does the same thing. Pass onbreak()
a pointer to a function that returns 1, or use "signal(SIGINT, SIG_IGN)"
which will do just that for you.

A check to see that you frequencies are lower than the low pass filter cutoff.
(Something like 7Khz) and second make sure you are setting the volume! If you
can find a copy get the "AudioTools" from Rob Peck which have some good 
example routines in them for accessing Audio functions. (They are part of
the 1988 Developers Conference Notes)

A most excellent question, it's the "which music program is best for me?"
types ones we'd like to leave in c.s.a.
