I had a brief thought that maybe one of the other lines need toggling 
today, but after reading your suggestion I had a closer look at the
schematic.

The !Reset line is being held high on the board, with a physical 
switch to pull it into reset mode.

Face-palm, doh!
Its one of those moments when you could just kick yourself,

Looking ever closer at the schematics of the prop plug and Sanguino 
board, its the RTS line that should be toggled, not the DTR which the 
prop plug uses.
So i'm not too sure how I can mod it, if I can mod it, by taking the 
pin from the connector and somehow solder it to a QFN package.
This is still quite pointless as i'm using a manual switch for reset.

I mean that the Arduino software doesn't know how to get the prop 
plug talking with the Sanguino.

If I can't resolve this, then i'll get a more compatible cable, which 
I just feed in with my next order of parts for my project.
