[Ham-Computers] Identifying Pin 1 on a DB-25 or DE-9 Sub-miniature D Seri...

[WA5CAB at cs.com]

Well, maybe the black dot means Ground.  But this is one of the reasons why 
I take anything gleaned off of the internet with several grains of salt.  
There is a DB-25 or DB25but there is no such thing as a DB9, DB-9  or DB09.  
As shown in any catalog of the latter part of the last century, it is a DE-9 
or DE09.  It is of course redundant.  That's just the way that the 
D-Subminiatures were originally set up.

But anyway, thatks for the info.
