You are correct Einar they do appear to be off by one bit.  I set up minicom to use 115200 8N1.  I have noticed that if I paste the command into the terminal and press enter, it works.  It seems to only happen when I type.  Here is how stty shows the serial port configured:

# stty -F /dev/ttyACM0 -a
speed 9600 baud;stty: /dev/ttyACM0
 line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

Since I have a workaround by pasting what's on the clipboard it's at least progress, but I don't know if this is actually preventing modem manager from working correctly.
