Read the RfC, it is: IAC DONT ECHO NUL, which means "Interprete as Command, Don't ECHO, termination of command". Send the values: 255 253 1 0 To the server. Do reenable echo, send "DO" instead of "DONT" . I don't remember, which command is "DO", but it should be one of 250-254, irrc. Alex -- I need a new ~/.sig.
