 		 #156815 - analog scope
Responding to: ???'s previous message
Change the code to output the same byte over and over. If you use 0xaa you should get a square wave. Check that the bit time is correct (104 uS).

As Daniel said, the rise/fall time should be much less than a bit time - no way it should look triangular.
