Using simple serial with arduino

PaulS:

What I have now seems to all work correctly over xbee and the pots are distinguished using S,B,G for steer, brake,gas pots.

That's not the impression I get.

I stated earlier everything was going good, no weird numbers or big jumps. I seperated the 'B' and 'G' to seperate breadboards and it get no interference with the two. Everything is good now with the pot outputs over xbee.

Now my main concern is getting it to talk over simple serial. I am using BMSerial.h and have stated BMSerial brake(5,6) and brake.begin(9600). I try to write to channel 2 of the roboclaw using brake.write(128) or brake.write(255) as for channel 2 the min is 128 and max is 255 to either apply forward or apply reverse on the actuator. It does not seem to be communicating with the 'write' to the roboclaw.
