Telegram Client Delphi

I need a simple Telegram client (with source code) written in pure Delphi for Win x64\ OSX. Without any 3d-part components (pure tcp) and external dependencies. I wll test it on clear windows XP installation. The client must: 1. Authorize in Telegram 2. Start receiving text only messages from every added channel (inc. personal messages) 3. Ping the Telegram server each second to decrease delivery delay. No GUI, no multithread required. A class with mentioned above methods would be enough. The client dont need to get image\voice and so on from messages; you even may provide a message JSON without parsing. ==Note== !!! I do NOT need a Bot but a CLIENT! Those who suggest a bot either cant read or just have no idea about the subject.
