Ah, thank you. I have been trying to remember that name since this
thread started. I've used extremely little DOS, but I remember seeing
LapLink in there. I think it could even bootstrap itself across a serial
port to a different machine, as long as DOS was installed. And then it
could copy pretty much everything else over.

Actually, the cables were straight through. The nice thing was that the
serial cable had both the DE9 and DB25 on both sides. And it was
combined with a parallel cable as well. So you had two cables and three
connectors on each side.
(Well, by straight through I mean that they were null-model cables.)
