[Dx4win] DX4WIN with M2 Controller

[ARS NZ3O (Byron) FM29fx]

I have an M2 2800 Azimuth controller that was recently
upgraded to the latest release of the main board.  When
I connected it back to the serial port on my PC I experienced
the following:
1. When I use "F11" to turn the antenna, only the first two
digits of a direction greater than 99 are used.  So, attempts
to turn to 330 result in the antenna pointing to 33.  The next
push of F11 results in no response.  The third push (assuming
you use a different azimuth) moves it just like the first push.
And so on.  (It seems like maybe the M2 protocol changed?)
2. When I use HYPER terminal, I simply type 330 and things
work fine.  This tells me the current protocol is <number><enter>.
Is that what DX4WIN has always used, or is this a change?

TIA, 73, Byron
