  The standard "Parallax Serial Terminal.spin" object does that. Within the Propeller Tool you can find the Propeller Serial Terminal Demo.spin program under the "Propeller Library - Demos" folder. Also, under Help in the Propeller Tool, you should be able to open the Propeller Education Kit pdf which covers some PST usage starting on page 102.
  
  What you are looking for specifically, is on page 106 and uses the "EnterAndDisplayValues.spin" code from the PE Kit folder.

  Hi Tom,
  
  Thank you for the feedback. I AM using the Parallax Serial Terminal.
  
  Can you give me a simple example of how to read the input from this into a spin program?
  
  Thank you!

  WBA provides some links above, and the short answer is

  ascii := pst.rx

  Thanks for your help. I figured it out myself. Now I feel dumb. Too easy...

  You may want to use PST's CharIn as it will wait for input (Rx may not)

  '
  ' Character input Example, using Parallax Serial Terminal
  '
  OBJ
  
    pst : "Parallax Serial Terminal"
    
  VAR
  
    byte x
  
  PUB Main
  
    PST.Start(115200)  ' baud rate on default UART pins
    PST.Str(string("Starting..."))
    PST.NewLine
    PST.NewLine
  
    repeat
        x := PST.CharIn       ' wait for character to be typed
        PST.Str(string("Character typed: "))
        PST.Char(x)
        PST.NewLine
