  You can set the baud rate the BS2sx uses through the 'baudmode' parameter. I find 9600 baud most useful, but you'll have to look up in the manual what baud-mode constant for the BS2sx corresponds to 9600 baud.
  
  The BS2 only does 8-bit, no parity or 7-bit, even parity. Again, selected with a flag on the baudmode constant.
  
  And if you use the 'programming' port, (SEROUT 16, ...) then I believe you should use 'Inverted' mode -- again, yet another flag on the Baudmode constant.

  Do you by any chance have any sample code that shows a visual basic and bs2 communicating?

  Funny you should ask...
  
  Please see the attached.· Note it is for a BS2, so you'll need to change the
  baud-mode constant for a BS2sx.· I keep saying this, because it can be
  really un-obvious to the first-time BS2 user, who typically puts a value
  like "9600" in there, expecting that to work.

  How do you reference the Sout Pin? You use S_out in your program and it wont recognize

  Well you can define "S_out" as:
  
  S_out CON 16
  
  and that should work. Or, you could have used the 'A' example, and it should work unmodified.
  But good catch, that.

  Oh sorry... I'm still trying to get a hang of all this.
