18x

Ok, so I finally got all my gear set up to build robot numero uno, but Im goin friggin nuts trying to control my continuous rotation servos from parallax. Im using a picaxe 18x to produce the code, but no matter what pulsout or servo commands I use, my servo's only go clockwise.I NEED them to be able to go counterclockwise  for my differential drive train to work right. I have read every post on LMR about servos and have tried a lot. I have read their parallax data sheet and that they should respond based upon the pulse width, but no go.

I just got my Pixaxe 18x starter pack in the mail (YAY http://www.sparkfun.com/commerce/product_info.php?products_id=8326) and the one thing that seems to be lacking is complete documentation. :)

All the output pins seem to go through the darlington driver and the pins coming from it are all negative (-) -- not positive (+).  Usually when you set a pin to "high" it goes positive, right?  This seems to reverse that.  I'm not exactly sure how to connect this to the motor driver or do serial output.   I hope this question makes sense.
