What helps? Making the baud rate higher than the software layers can
handle? You must be kidding.

Actually, I seem to remember the OS doesn't support 115200 baud at
all, be it through the 'mode' command or through DOS API calls. The
difference being that 'mode' will probably not even inform about its
failure to actually set that baud rate.

Then you're SOL. In particular, you should throw away and forget all
results from communication tests you made under XP --- they have
essentially nothing to do with what you'll see on real DOS.
