Hello,
I am having a hell of a time getting serial output from serialice on a 
Winbond W83627HG. I have tried everything I can think of and hoping
someone on the list will be able to help or have suggestions.

Note I do get garbage serial output:
-----------------------------------
Welcome to minicom 2.5

OPTIONS: I18n
Compiled on Jan 31 2011, 09:58:19.
Port /dev/ttyS0

Press CTRL-A Z for help on special keys

�����������������������������������
----------------------------------

Normally when you get garbage output is is because the baudrates are
wrong, but both of my baudrates are 115200 in serialice and host PC.
Also the serial console works fine with vendor bios and Linux.

Things I have tried:
Tried changing from COM1 to COM2, still garbage output.
Tried adding port 0x80 posts and it gets all the way through the
mainboard code.
Tried changing SuperIO config port from 0x2e to the alternate 0x4e (no
output at all).
Tried changing CLK from 48Mhz to 24Mhz (no output at all).

Attached is my mainboard config and superiotool output, please take a
look and see if there is anything you could suggest. Thanks in advance.
