- Toby - while not having read the standard, years ago I was reading a
- book on RS232 and it was detailing the pin connectors for a DB25.
-
- I believe there were 6. What I found amusing was the the 6th
- 'standard' was that pin 7 shall be signal ground, all others to be
- user defined.
-
- Using that as a guide, I have yet to find any RS232 that didn't meet
- the 'standard'.
-
- Is that actually part of the connector specs?
