When Telnet protocol is used, echoing is performed by the host. The host has complete control over the echoing. The control is gained by the host by negotiating the TELNET ECHO option. If this option is not negotiated then echoing is handled by the local application.
If you have replaced Telnet with raw TLS and have not changed the application in any other way, the client is probably performing echoing. Although, there is no reason why you can use Telnet protocol over TLS. > Marcos, > > I dont see what obtaining input from the user has to do with > OpenSSL?
