Hi, USOCKET users WAIT-FOR-INPUT support for ECL/win32 has been committed to USOCKET trunk [1] today, this make ECL being our full supported platform. If you have a USOCKET application used running on UNIX platform, now you can try to run it on Windows! Let me know there's any issue left. Your help will definitely make USOCKET project better and faster to release next version. P.S. Current known full supported CL platforms by USOCKET on Windows platform: * Allegro CL * Clozure CL * ECL (new added) * SBCL (new added) * LispWorks * ABCL (lack of UDP support, in progress) Regards, Chun Tian (binghe) [1] svn://common-lisp.net/project/usocket/svn/usocket/trunk
