The  pinout described in RS-530 is the closest to an actual standard
for V.35 on a DB25. I beleive that there are small differences in
termination impedance, but from my experience, tend to work fine
together.

Lots of vendors have adapters from winchester to db25, but they arent
necessarily the same pinout..  The smart ones have followed the 530
pinout..

By the way, I absolutely HATE those V.35 connectors *grr* (rumor has
it that the inventor of the connector is widely sought for a public
lynching)
Be careful, as the spec for v.35 was changed in 1984. The old V.35 was
overwritten by a V.11 based electrical spec.  Very close, but there
are differences (a small piece of interface trivia)
