how to stop at an internal Maple proc?

I want to see how Maple determined the type of an ODE. But can't set break point at internal Maple proc:

restart;
ode:=2*sqrt(a*diff(y(x),x))+x*diff(y(x),x)-y(x) = 0;
DEtools:-odeadvisor(ode);
      #[[_homogeneous, `class G`], _Clairaut]

But when I do 

 stopat(DEtools:-odeadvisor);

it gives erorr

Error, invalid input: stopat expects its 1st argument, p, to be of type {`::`, name, string}, but received proc () option `Copyright (c) 1997 Waterloo Maple Inc. All rights reserved.`; `ODEtools/initialized` <> 'true' and `ODEtools/init`() <> 0; `ODEtools/odeadv`(args) end proc

Is it possible to set break point at DEtools:-odeadvisor? showstat does not show much. I thought it was possible to view all Maple library code (other than the builtin ones).

But may be some are not possible to see in addition to the builtin? How does one know then which one can see and which one can't see? How one see the code the DEtools:-odeadvisor?

Try this,

restart;
ode:=2*sqrt(a*diff(y(x),x))+x*diff(y(x),x)-y(x) = 0:

showstat(DEtools[odeadvisor]);

stopat(`ODEtools/odeadv`);

DEtools:-odeadvisor(ode);
