[RTTY] Radio stops sending messages

ALWAYS, ALWAYS, ALWAYS, set Comm PTT: NO.  

Writelog does not time the RTTY data but simply dumps it 
to the buffer. When Writelog has finished dumping data to 
the buffer it drops PTT (sends a PTT OFF command via CAT). 
It is the CAT PTT OFF that is causing the FT-2000 to stop 
transmitting before the message is finished. 

BTW, with WriteLog it is usually wise to add a couple  
spaces to the end of every message to provide a bit of a 
tail to prevent a "too quick" PTT drop.

MMTTY always asserts PTT on the FSK port (in previous versions 
of MMTTY, the "FSK" port on the TX tab was even labeled PTT 
Port).  Router never handles PTT independently, it only passes 
the status of DTR on the FSK or PTT ports.
