I am trying to use undump on a program that uses the fpa.  Undump works
fine on the version of this program that uses the 68881, but seems to hang
the first time the fpa is used.  I'm actually not surprised at this, since
the fpa is a device (rather than a tightly coupled co-processor like the
68881), and is probably accessed by doing some open-file like operation.
My question is, what do I need to do in a program to re-initialize the fpa
so that my undump'ed program will work?  I've checked the Floating Point
Programmer's Guide, as well as the fpa manual, without finding what I
need.
