So I am still a little confused, sorry. The 6 pin header that you are talking about, is that the 6 holes on the lower part of the board? I had thought about if the lines coming off the 60 pin header were un shifted?

Based on the schematic the BT signals to the 6 pin 0.1" header are not level
shifted through the ICL3232 device. The RX and CTS signals do go through a
series resistor though, the TX and RTS go straight to the 60 pin header.

Subject: [Gumstix-users] Question about Un-Level Shifted RS232 on Console VX
I am trying to connect to un-level shifted tx and rx of the BT (ttyS1)
serial port on a R1753 console-VX board. I have a few questions. 1. Are
the un-level shifted tx and rx lines for the ttyS1 brought out on the
breakout board that you can buy from gumstix? 2. Is there an easy way to
solder to any point where the signals are un shifted? I noticed that there
seem to be a series of through holes labeled on the back of the board. the
BTUART has 6 connections, but I assume those are level shifted. I don't
have access to a scope at the moment and wondered if anyone knew what those
