If you are having problems downloading from here (using HTTP) then you can download using FTP from Sunfreeware. Also, if would like dio for a version of Solaris that is not available here, then try sunfreeware.com
The C source code (dio.tar.gz) is available under the GPL license which embodies the spirit of invention, trust, developer credit and knowledge sharing that has allowed UNIX, in all it's various forms, to be so successful. The other main reason that I have done this is so that my code can be subjected to the full scrutiny of the UNIX community, which I think can only be a good thing.
Version 1.6 of dio is available here. It includes an option to run dio in the background. Please test and let me know if you have any problems. Only available in source form just now.
Please send me feedback if you download dio.
