note: I’d like to thank Peter Baker for his guidance.
Peter was one of my teachers at Langara College. The
feared and revered ACST program featured hands-on approach
to hardware. Peter lent me his GPS and gave me a C for
this project because I made the same mistake twice.
I forgot that the null modem cable needs a gender changer.
On
July 31, 2005, Brad Zdanivsky became the first quadriplegic

Columbia. In addition to rock climbing, Brad’s interests
include Java and embedded systems. For more information
