Remote Debugging
Stephen Keung
support via serial port, with the host platform being W2k and the target
being 32bit-DOS. The feature page on openwatcom.org seems to imply such
a debug setup is doable, but I don't have much luck with it. Besides
this page, there is not much new documentation in the area of remote
debugging setup since Watcom v11.0. Any help will be appreciated.

I don't think it is doable. The serial support is not for Win32. But it
should not be hard to do. All that is required is a Win32 driver.
It might be doable in 3 stage not 2.
