[GreenKeys] [Bulk] Re: C-64 to drive Mdl. 15 TTY (and probably others..)

GN OMs;

There are several reasons for doing CR CR LF LTRS LTRS:

o Give old machine time to get back to the left side and
   everything to lock up.

o Gives a little extra protection in the event of a static
   crash during the first CR.

o I was told the sequence was CR LF CR LTRS LTRS when I got
   involved in RTTY - because the 2nd CR was 2 characters
   from the first CR.
