  The 0x0d is treated as a hexadecimal number and converted to a carriage return.

  
  Not on the Prop. It needs to be $0d.

  I just noticed you're using the same pin for tx as rx. I don't think FDS can do that, but I'm not sure.

  But if I'm just sending commands....should I only use the tx pin?

  Doh, you're absolutely right. Too many compilers/assemblers under the bridge.

  The following code should turn on motor #1 at half speed. Pause three seconds and stop the motor. It should then turn the motor on at full speed for another three seconds.
  

  OBJ
    pst : "FullDuplexSerial.spin"
  CON
    _clkmode = xta11 + p1116x
    _xinfreq = 5_000_000
    TxPin = 0
    motor = 1
    speed = 1000
  PUB Main
    pst.Start(TxPin + 1, TxPin, 8, 115_200)
    waitcnt(clkfreq + cnt)
    repeat
      pst.Str(String("!G 1 500", 13))
      waitcnt(clkfreq * 3 + cnt)
      pst.Str(String("!G 1 0", 13))
      waitcnt(clkfreq * 3 + cnt)
      pst.Str(string("!G "))
      pst.Dec(motor)
      pst.tx(" ")                  
      pst.Dec(speed)
      pst.tx(13)
      waitcnt(clkfreq * 3 + cnt)
      pst.Str(string("!G "))
      pst.Dec(motor)
      pst.tx(" ")                  
      pst.Dec(0)
      pst.tx(13)
  
  

  
  I use "8" to turn off the rx echo instead of the binary number since the forum software messes up the binary unless you use the basic editor.
  
  Edit: I just saw you got it working good. It's times like these I regret having never learning to properly curse.

  I'll try this out now.
  
  But it was the clock statement and the ,13 works.
  
  Let me give this a try.
