I assume the different types (PcAnsi, Vt100, Vt100+, VtUtf8)
just make EFI use different escape sequences.  So pick one
that corresponds to the terminal emulator you're using.
I use xterm, and I usually use a Vt100 or Vt100+ flavor.

If you change this flow control to "hardware", does it
make any difference?  I hope that MP doesn't limit LAN
connections to 9600 baud based on the config above.  If
it does, you probably want to change the baud to 115200
as well.
