OK, I am having several small problems.  First of all, I have two programs.
A program A and a program B.  It appears that if program A has the
serial.device allocated in an exclusive manner, and program B tries to open
it once, in either exclusive or shared mode, program B is locked out and
errored.  If program B tries to open it TWICE, it opens!  I can't figure
this out, and for all I know, it may just be something stupid I'm doing.

I want an interrupt to render graphics into a RastPort inside a window.  I
need to know when the layer is locked, so I won't draw into it and cause a
lockup/crash/guru whatever.

Thanks!
