Why would you expect any updates? The technology behind the parallel port has not changed since 1994. Actually, the web page has remained the same, but the code base has been updated more recently. On the down side, this implements only the SPP interface. It doesn't do ECP or EPP, which means you can only input from the 4 status lines; you can't do true bidirectional stuff. Also, you'll have to locate the "giveio.sys" driver in order to access the I/O ports, which probably excludes 64-bit systems. It's getting more and more difficult to find machines with real parallel ports. (Pyparallel won't work with a parallel/USB adapter.) If it were me, I would forget about the parallel port and get a simple USB experimenter's board. Many of them come with a large set of GPIO lines. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
