(Note that I don't know Ada and have never use Alsys, but I enjoy
DOS.)

A lot of VMs have bugs and omissions because DOS isn't used nor wanted
nearly as much as other OSes. I'd be surprised if debugging
(presumably 386 hardware debugging registers) was fully supported nor
serial port stuff, etc.

I honestly can only suggest you use a different VM (though I know
VirtualBox has bugs, ugh, hope you have VT-X).

And (at the very least!) be sure to ask in one of the DOS-oriented
groups like news://comp.os.msdos.programmer or even on FreeDOS'
mailing lists (e.g. freedos-user). I know at least two guys in FreeDOS
use VMware a lot (Bernd, Eduardo), so it can't hurt to ask. And
Japheth is the resident debugging expert there.
