I've heard about this product and it sounds like the only problem that
could come up is if I want to use the DSP for something else.  Also, if
I'm playing music that uses the DSP and this is attached and active,
could there be problems?  I heard that 3.0 will be able to combine sounds
from different applications, and to me this sounds like a job the DSP
would end up doing.  Is that so?

The only serial add-on I know of is an 8-port thing from UNINET (I think
that's how that is spelled), but I just need one high-speed port.  Any
suggestions?

Thanks for the information.
