    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.
