Not sure what you mean here... if the API is set in stone, then how can the module be improved? Internal checks on the bit? But that could change the semantics of the API without changing the interface of the API -- not clear that is helpful... just make a new parallel API if you need to handle both binary and text data. -- Glenn -- http://nevcal.com/ =========================== A protocol is complete when there is nothing left to remove. -- Stuart Cheshire, Apple Computer, regarding Zero Configuration Networking
