I looked into it and it seems the AOL TOC servers have been turned off by AOL on September 10th, 2011. The TOC servers were made for 3rd party programs to connect to AIM and AOL has decided to end support for this system. I will have to remove the Hal AIM Bot from future versions of Hal as it will no longer work.
AOL's official servers use a protocol called OSCAR which has been reversed engineered. But I think that if in the future we decide to support IM bots, I will make a plugin for trillian ( http://www.trillian.cc
) rather than a standalone client. This way it will support a wide variety of IM systems (MSN, Yahoo, Skype, AIM, ICQ, etc.) and the actual server communication protocols will be maintained by the trillian people.
