If so then you should have pins set low for both high and low signals and toggle the port direction from input (high signal) to output.low for the low signal. The basic stamp code uses HIGH CS_8255 where normally you would switch the output low on the CS to input highz to allow the pullups to pull the line high. Like I said Its 2:30 and I am just trying to get out of here but I thought i would toss that out there.
