Hi, I believe, that the problem is, that you didn't implement Telnet protocol. Let me inform you, that Telnet does not just assume sending and recieveving text messages. It contains much more commands (I mean protocol commands)... I believe, in your case, the server on the other side configured to send some escape sequences to configure client (For example to configure session parameters such as color). My suggestion will be to take a look at Telnet RFC (Unfortunatelly, I don't remember the number). Regards, Hovhannes

А по мне, скорее 80 ненормален, чем 23. Было бы логичне было встретить бинарный application layer protocol, чем ascii по стандарту telnet. HTTP, FTP, SNTP... текстовые, и вообще на человека расчитаны, а не на машину...
