>USB-to-serial adapter (for GPS) and latest Prolific drivers

Our Prolific chipset based USB to Serial adapter was reviewed on a Google Group discussion. My impression from the discussion is that Prolific is a mid-line chipset that behaves well in the latest Microsoft OS and works well under most circumstances. Huge Pine is a less expensive chipset, but quality control and/or software drivers are an issue. The FTDI chipset is apparently less problematic than Prolific according to one forum poster.
