I read somewhere, this 9-pin-Layout is a little bit stolen from the old SGI
machines. They had this connector long before the PCs, and the layout is nearly
the same than the PCs have. So this needn't be just a space-problem.
If you have a DEC H8571-J, the problems are gone, this is the MMJ-DB9 adapter.
