I have created a Telnet server thread (this server thread listens at some port e.g. 1234) which is running inside a Kubernetes container. Inside the Kubernetes container, I execute command telnet 127.0.0.1 1234 to create a telnet connection to that port running inside that Kubernetes container.

I am able to get the telnet prompt but when I type any commands in telnet prompt e.g. "help", the characters "help" are NOT getting displayed in telnet prompt.

telnet Client Version is telnet-0.17-66.el7.x86_64
