That's right. Known bug with MMTTY Plug-in and XMMT coexistence in WriteLog
11.10G. Work-around is to remove the MMTTY Plug-in.

You can only set the COM port in either the Rttyrite Port menu or the MMTTY
Options/Setup/TX window. Trying to set a COM port in both will elicit the
error message above.
Setting the COM port in the Rttyrite Port menu uses WriteLog's WinRtty
encoder. By default, WinRtty uses "Hardware generated FSK" and that will be
checked at the bottom of the Rttyrite Port menu. You can choose "Software
generated FSK" instead, especially if hardware FSK doesn't work well for
you.
Setting the Rttyrite Port menu to "None" and then setting the COM port in
the MMTTY Options/Setup/TX window will use MMTTY's FSK facility instead of
WriteLog's WinRtty FSK.
