The problem is that launching a DOS program from a Win32 shell creates
a new DOS box, so you can certainly run a TSR in there but your app
won't be able to access it since it won't run in the same DOS box. So
yes, you need to start the TSR from a DOS shell. But I suspect that a
real DOS emulator may be a better choice for your app than Wine.
