I am using the StandardFirmata to communicate to Arduino from Processing. How would I tell Arduino to send commands from it's TX port to my servo controller (Mini Maestro)? I can use all of the analog/digital/pmw pins but I do not see how to use the TX1 or RX1 pins. My Arduino board is connected to the computer via USB. I want to be able to write to Serial1.
I have a method for using processing, Arduino and the maestro together but I am trying to avoid programming in two locations (Arduino and Processing) and just doing all of it in processing and using Arduino as the middleman.

You can't. You are using the TX/RX pins to talk to Processing.
Even if you weren't, when you installed the Firmata sketch, you removed the brains from the Arduino. It can only do what Firmata knows how to do, which is limited to reading and writing to analog and digital pins, and moving servos.
Sorry this is a late response. That makes sense for what Firmata does. I figured out another way to do what I wanted without using Firmata. Thanks for your input!
