It then shifts everything from that point on to the beginning of the buffer and reads bytes until it sees the WMO end-of-message character sequence (CR CR LF ETX) or until end-of-file (whichever comes first). While this is happening, the buffer is expanded, as necessary, to accommodate more data. Once the end-of-message or file is seen, everything in the buffer up to that point is the WMO message, which is then converted into an LDM data-product and inserted into the product-queue. The problem with the files in question is that they don't contain a WMO start-of-message character sequence. Information on the format of a WMO message can be found at http://www.nws.noaa.gov/tg/head.html.
