I'm happy to answer YES to my own question :

  #include <dpmi.h>
  
  __dpmi_regs regs;
  regs.x.ax = 0x168b;
  regs.x.bx = 0;
  __dpmi_int(0x2f,&regs);

This is documented in Ralph Brown's interrupt list as available for
Windows 3.1, but still seems to work with Win95.

By the way, I don't know how to reverse the behavior...
