[GreenKeys] series of "N"'s

[Sheldon Daitch]

We (VOA) were part of the abnormal world and perhaps still are,
but in the long ago days of real TTY and paper tape, we
used the NNNN for end of messages and the reperfs
on the receive side were set up to stop punching tape on
the NNNN....actually they would stop on the third N,
if I remember it correctly.

We weren't a net operation, but a point to point
system, with Greenville VOA as the hub for the
daily RTTY schedule, so all message traffic was
punched.  To start the reperfs, we used FAXFAX
and in fact even today, we still call our record message
system the FAXFAX even though it has nothing to do
with the TTY system.
