Ah, OK - I've got you. You also need to run the script once you have launched rtl_tcp using the command in step 3) below.
The simplest way to do this would be to add a step: 6) Sign in to rPi with a new terminal session, leaving the old one open for now. cd to the directory where you created the script and then run it using this command: ./rtl-robot (or whatever you called the script) You could run the script from the same terminal that you launched rtl_tcp from if you used & to force rtl_tcp to detach from the console and run in the background. I'll edit the comments on the script to make that a bit clearer... Thanks!

At the moment i've taken another approach...i've patched the rtl_tcp.c to set the gpio directly...i'll post my "project" asap somewhere...
