In your OnComm event, read the input to a form property and test for the CR in the property.

*** ActiveX Control Event ***
#DEFINE _end_char CHR(10)

WITH THISFORM
  IF THIS.commevent = 2
    * Received RThreshold # of chars.
    .cinbuffer = .cinbuffer + THIS.input
    IF _end_char$.cinbuffer
      * Got a CR, so do your processing here
      * to extract the complete string and leave any
      * remaining chars in .cinbuffer.
      * Better yet, create a form method to
      * handle the extraction and cleanup:
      .processdata
    ENDIF
