in your linux console, run "stty -a" and in this output look for "onlcr" or "-onlcr" !

for my (non-openmoko) linux this gives

	stty -a | grep onlcr
	opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0
	                    ^^^^^

where the man page explains

       * [-]onlcr
              translate newline to carriage return-newline


that's why a single \n results on \r\n on a real terminal, this is 
standard unix termial behaviour for the last decades.
and it's standard unix that you can change this settings -- just try

    stty -onlcr


so yes, \r\n *is* the correct output at the "more physical" layer...


have fun,
