Hey Folks,
I'm trying to use the roSerialPort object and I don't seem to be able to find the syntax for actually determining what byte I've received. I can test for the event type no problem (if serial event then turn on light....) but I don't seem to find any syntax which allows me to determine what character I've actually received. For video object message (for example) I can perform a "GetInt()" and determine the video message number (8 for finished...that sort of thing). What syntax do I use to "Get" the ascii character once it's been received? Any help would be awesome..thanks in advance.

  You can just look at the the message itself. And, if you are receiving bytes and not strings, be sure to use SetByteEventPort(p) vs SetLineEventPort(p)
  
  
  
  For example:
  
  
  
  msg = wait(0,p)
  
  if type(msg) = "roStreamByteEvent" then
  
    if msg = &H0D then print "carriage return received."
  
  
  
  endif

  Aaaaahhhhh....thank you Lyndon.  That worked like a charm.  The hint of using a hex value and not ascii in quotes is what did it.

  Hi,
  
  For UDP received strings, we would do the same in order to catch everything to last hexadecimal 0D?
  
  Thanks

  UDP only receives strings, and it doesn't require a carriage return. You could take in the string, and then check if the last character was a carriage return.
