and I have NEVER seen a DE15 used for any kind of serial.
Considering that these cables probably came from an LCD projector, it is
PROBABLY a monitor adapter of some sort.
Somebody clueless may have looked at the DE9 and automatically labelled it
as "RS232" (as a misuse, meaning serial)
My assumption, actually, is that it's a custom peripheral
adaptor for the projector. The presence of ADB and PS/2
ports would make me guess that it's so you can attach a
mouse (some projectors used it for their config screens,
others let you control the host machine's cursor through
the remote, which would indicate the other direction).
The DE9 is probably for a serial mouse (which I recall
being pretty popular before PS/2 was ubiquitous).
