5 volt is cmos level, which is fine for what i am talking to.
question is can i use interrupts to control the pins for the right baud rate

You won't be able to bit-bang serial out through the DS outputs. The DS outputs are updated by packets sent from the crio at ~50Hz, so that's the fastest you can change them and read them. Since the only code you can write runs on the crio and not the DS, there are no interrupts for input pins on the DS that you can take advantage of.
The only way I can think of that you could interface a serial LCD to the DS would be to build a custom board that would receive signals from the DS outputs and translate that to serial, or use another board that could use Ethernet and receive the dashboard packets, parse them, and then connect to the LCD for display.
