COM PTT is a very bad idea in general.  However, if you are using the
MMTTY plug-in it generates its own PTT on the RTS and DTR lines of the
FSK port.  If you are using the Plug-in add a second transistor driver
on either the RTS (preferred) or DTR line (see the excellent info by
AA5AU here: http://www.rttycontesting.com/tutorials/tutorials.htm
and here: http://www.aa5au.com/rtty.html)
