ok I am sure its an easy .. fix and I cant see it.. but here it goes

I have the ramp script running for my sabertooth on D7 and it works great ( thanks Rich)

However, I have my R2's dome going to a syren 10 that is hooked to D8 and I am having difficulty getting it to work... I have the Movement Panel used up for the sabertooth... I thought I could just use sendserial (port,baud,data) in separate script to move dome. This is not working.. I can just test with sendserial (d8,34800,200) and It just says "done" but nothing happens.. What is the issue ? how can I control the syren and the sabertooth in same project ?
