DCUTerm only Shows <0>'s

Everything is connected and configured per the start guide and I get a response on screen but its all 0's. What am I missing? I expected to get into Nboot or Eboot by pressing S key but no response. Just lots of <0> that eventually stop when you see the desktop on LCD. Thanks

Ive tried all different Baud Rates with same results. Im using a windows 7 workstation I keep around and has a physical PCI 2 Serial (RS232) Ports / 1 Parallel port (startech/amazon) which works for other similar applications. Ive attached pictures of my settings. By all accounts this should be working and it responds when I power on but Im not getting actual data I expect, only <0> . Your help is appreciated,

My setup

That did work, thanks. It says AUDIO on the board with an arrow to that header.

Are you at all familiar with the board combination in the attached picture? Its a German manufactured printer that uses the PicoCOM5 board as part of its OS and we have been having a lot of issues with boot failures or file system becoming corrupted. We purchased the PIcoCOM5 starter kit in hopes that we could shed some light on these issues by looking at the boot up sequences and hopefully be able to store or clone good working units to bad ones to try and salvage them. The manufacturer has provided no assistance with this issue and at $5,000 per replacement board (est. 15+ units) our customers are getting upset and we would like to help them.

I tried using the DCUTerm program on the 10 pin header in hopes that would be a debug port but I get constant <0>'s while the printer is powered on.
Any help would be greatly appreciated.
