As far as I know, TDCC isn't documented anywhere at all, so here is what you will need to know: 1. TDCC uses CTCP DCC TSEND instead of CTCP DCC SEND. 2. TDCC always sends the file size. 3. TDCC has no formatting of the data stream.. the file itself is sent, with no interruption. 4. With the regular DCC protocol, the sender closes the connection. With TDCC, the *receiver* closes the connection when it has received the full amount of data. Note that (last I heard) BitchX does not comply with #4, and panasync refuses to implement it correctly. -- / Jesse "Monolith" McGrew \ PhongNet: IRC by youth, for youth. | jmcgrew at cris dot com | /server toldyouso.com 6667 \ Mr2001 on IRC / http://toldyouso.com/~mrircd
