cat will read its input in canonical mode. That's not really fun
to drive a shell/interactive program on the telnet remote session.

The only way I see this being possible is with "expect". Because
expect has the "interact" statement that can connect the user
keyboard back with the spawn'ed program in non-canonical mode.
