[RTTY] K or carriage return

There are several commercial interfaces that use a parallel to serial
shift register to generate FSK.  Those interfaces *do not* support PTT
on the same port as the FSK output ... instead PTT needs to be done on
another port (generally by the logging software rather than MMTTY).
Since the shift register introduces *at least* one character of delay
a single space is not sufficient.

If one is using MMTTY with EXTFSK on a simple USB to serial converter
or an interface that supports PTT on the FSK port, then two spaces are
probably a good choice.  However, with other interfaces a third space
is a good step for reliability.
