Not 100% sure, but I thought the command was transport input none.
As previously stated, transport input none will disable telnet.
But why do you want to disable it?

for PCI requirments they need to disable telnet
from transport input none
but i can still telnet, and it says password not set
that means port 21 is still open, and password is not set

This will not allow any telnet access to the device (will "stealth" the port).

Routers
A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
