Yes.

Yes.

POSIX has to be enabled and the Classic API tasks have to have their signal
mask changed from the default.  POSIX threads and Classic API takss have
different default signal masks.  By default, Classic API tasks do not 
have any
signals enabled because the API used to create them doesn't know anything
about POSIX signals.  If you as an application programmer want to handle
POSIX signals from a Classic API task, you just need to enable them.
