dos_setvect prob in WIN16

I have a WIN16 DLL written using msvc 1.52 and I now want it to be able to revecter an interrupt to my own ISR.  I was planning on using the _dos_getvect and _dos_setvect calls but where getvect seems to be ok., dos_setvect fails the link as an unresolved external.  A quick check in the lib files and dos.h revealed that the setvect function is specifically excluded for WINDOWS apps, even though the on-line docs indicate that it should be ok. for WIN16 and WIN16 DLL's.  At first I assumed that the on-line docs were incorrect, and that there was some good reason for dissallowing that call, but then I discovered that the Borland 4.5 compiler does not have the same restriction.

So the question is:  If dos_setvect is not the correct way to revector an interrupt in a WIN16 DLL, what is?

Assuming this is not a system reserved vector, you can just write the 3 line stub assembly file and make the INT 21 setvect call.  Works fine from 16 bit code under win 3.1.  I can write that code for you if you wish to ask another question :-)
