Yes, sorry - I see what you mean (just looking at 'stty -a' output in a 
shell window; icrnl is indeed set).

For the purposes of trying this board I'm unsetting ocrnl on the serial 
device, however (both in my C code and when I've been attempting to write 
directly from a shell), so it shouldn't be doing any translation when I 
send 0x0d down the line.

In theory, anyway! (I'm not sure if I have any RS232-capable dot matrix 
printers, as otherwise that might be the easiest way to verify what's 
actually coming down the line)

cheers
