>Since your RThreshold is 1, I'm assuming you are using event driven processing. Let me see your Oncomm event code.

Oncomm event code (really simple, just like other stuff):

  THISFORM.Edit1.Value = THISFORM.Edit1.Value + THISFORM.OleControl1.Input
  THISFORM.Edit1.SelStart = LEN( THISFORM.Edit1.Value )

>Will your cabling/DEC hardware support CTS/RTS hand shaking? Not your problem, just the way I like to do things.
I pretty sure it doesn't, the control wouldn't work with that setting anyway, I haven't checked on the DEC yet if there is something I can change to support it. I know it uses XOn/XOff, and that works.



>Since I can't see any extra data on the wire here, I think I would try and parse the data returned and see exactly what the DEC is responding with. The garbage in an edit box is not very useful. See if you can determine what exact control sequence is returned.

Here is what is being returned, I don't know what it means though:
CHR(30) + CHR(8) + CHR(27) + CHR(53) + CHR(30) + CHR(8) + CHR(27) + CHR(53) + CHR(27) + CHR(35) + CHR(27) + CHR(34) + CHR(30) + CHR(8) + CHR(27) + CHR(53)

Thanks again Jim,
