  The Stamps are certainly capable of "spitting out data" through the onboard serial port and it does work. There must be something about what you're doing or how you're doing it that's preventing it from working. You're going to have to supply more information if you want someone to make suggestions or try to help you to figure out how to do it successfully.

  Program is on another PC, but here's all it does (basically the sample code):
  
  Takes a reading from the Accelerometer every 200ms, and sends this info to the Debug window. I send my info using the DEBUG command, and I was hoping I could catch that info in a terminal program, such as procomm or hyperterminal. I've set up my com settings same way as the debug settings. 9600 n 8 1, I've tried no flow, hardware & software. Even if this was wrong, I should still see some garbled info coming across, correct? I don't even see anything in the activity window of procomm.
  
  So what I want to figure out, is there a difference between how the editor sees this info compared to a reg terminal app?

  The debug Window is nothing more than a terminal window. There's no reason you should see a difference. I do huge amounts of data comms using DEBUG, and I have no ideas. Sorry for the post about nothing, but just wanted to point out there SHOULD be no difference.

  Exactly what I was looking for, thank you. I've gone through the help a couple times and didn't notice anything special. I'm probably missing just a minor detail that's been starring me in the face.

  Hi SiCC, you still have not posted the code you are using, this is as simple as it gets , is this along the lines of what you are using?
  
  
  
  ' {$STAMP BS2}
  ' {$PBASIC 2.5}
  
  main:
  SEROUT 16,16468,[noparse][[/noparse]"A","B","C"]
  PAUSE 100
  GOTO main
  
  good for hyperterminal at 9600

  I dug a little deeper and found a post by PJ Allen from about a year ago. He suggested to make your own serial cable with just transmit, receive and ground. Something to do with the DTR pin putting the stamp in perma reset mode (Probably due to my stamp being pretty old).
  
  Works great. Thanks for the replies everyone.
