With microHAM DigiKeyer II, microKEYER II, MK2R+ and micro2R there
is no option to use DTR or RTS for FSK.  The solution is to clear the
"stuff" box in Router's FSK/2nd FSK port.

DO NOT attempt to use 2Tone FSK and MMTTY at the same time - one on
the FSK port and the other on the 2nd FSK port.  Applications that
use the UART buffer (COM port register) and those that toggle the
TxD pin directly (Set BREAK/Clear BREAK) are incompatible.
