Hi all, thanks to Blair for telling me about HXRT and big cheers to
Japheth for his HXRT DOSX variant :-). So yes, DOS boxes work in
WIN /S (only full screen DOS boxes, which are suspended while they
are not the foreground task - classical WIN /S style imho) with his
DOSX in FreeDOS :-). Note that SHARE must be loaded.
DSWAP hooks, in a dos box: int 8, 9, a, b, d, e, f, 10, 15, 16, 1c,
21, 27, 2a, 2f, 5c, 70, all IRQs, VGA, int15, keyboard, timer, DOS,
multiplex and int 5c...
A dos box has the comspec contents upcased and adds a variable
windir=C:\WIN..., note that the variable name is lower case.
Layout of test results did get messed a bit, repeating:

PS: Tested with FreeCOM 0.84 German Aug 28 / Kernel 2035 default May 2004
on a German Windows 3.1 with some MS y2k / mixed patches installed. And
tested with a pile of drivers loaded (cd-rom, moresys, caches, mouse...).
Seems to work equally well with and without emm386 loaded.
