[RTTY] Addendum Re: [WriteLog] N1RCT's interface page still avail

[WA9ALS - John]

I guess I should add 2 comments:

1.  Dick's diagrams use DTR instead of RTS for PTT - This depends on which
software you're using.  WriteLog has PTT on RTS and CW on DTR.

2.  Dick's page also shows the pinouts for both the DB-9 and B-25.
