I think this must be a FAQ, but here goes.  Is there a generalized
way within an application to determine whether there is actually
a device attached to a COM port?  I know you can try to initialize
the port and check the error code, but that has a very long timeout
period.  (Like 15 minutes on my Gateway.)  Does anybody know a
faster way?

Thanks.
