Be aware when using 2Tone FSK with some interfaces boxes using the
TxD option can result in a problem. Because 2Tone toggles the TxD
line there is no character information going into the interface COM
port register. As a result the interface box starts to feed idle
characters into the TxD line via its UART. Net result is corrupted
FSK. Two solutions: either use DTR or RTS for FSK, OR change
interface box's setup to turn off idle characters.

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.

The updates are to do with the logger interface. No change to decode
efficacy.
