- 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)
