== TOC2 ==
The '''TOC2 protocol''' is an updated version of the TOC protocol, or "Talk to OSCAR" protocol. Its existence was never documented by [[AOL]] andAOLand it is only used in a few [[AOL Instant Messenger]] clients. Some clients are beginning to offer plugins for TOC2 in light of AOL's recent shutdown of their TOC servers. Like its predecessor, TOC2 is an ASCII protocol and lacks some features of [[OSCAR protocol|OSCAR]], but unlike TOC, TOC2 is known to support [[buddy icon]]sicons and receiving file transfers (not sending). TOC2 operates in essentially the same way as TOC, as a wrapper for OSCAR. [[Porting]] code from TOC to TOC2 is remarkably easy as well.
Because of the similarities between TOC1.0 and TOC2.0, they are better defined by their differences, of which there are only a few: In TOC1.0, connecting with an empty buddy list would make it so that others are not able to see you online. This has been corrected in TOC2.0. In TOC1.0, there is a toc add deny command, but no toc remove deny. TOC2.0 corrects this as well. The sign on process is basically the same as TOC1.0, but with a few new parameters: version, a number, and a code created based on the username and password. The purpose of the number is unknown. The default and it seems to have no effect if changed.
Permitting and denying have been and are much easier and full-featured in TOC2.0. The commands toc2 add permit, toc2 remove permit, toc2 add_deny, and toc2 remove deny are all present and accessible at any time. Buddy list commands have also been improved management is easier with the toc 2 new and toc 2 del commands. Also, it is possible to add or remove more than one buddy at a time, and choose the groups they are in. A few syntax changes have also been made, and parameters have been added to some commands. The uses of these parameters are still undetermined.Aside from this the only changes from TOC are the fact that a was added on most commands both CLIENt SERVER and vice versa UPDATE BUDDY2, etc.TC2 also Screen Names that can log in from a single IP address

* Aside from this the only changes from TOC are the fact that a '2' was added on most commands both CLIENT->SERVER and vice versa. E.g. IM_IN2, UPDATE_BUDDY2, etc.
* TOC2 also limits the number of ScreenNames that can log in from a single IP address (10).
