Running as a daemon and providing interactive I/O are
incompatible goals. A daemon is a program that runs
in the background without a tty.

If you need a way for a user to control your daemon
from the command line, use a regular interactive
program that communicates with the daemon using
some IPC mechanism.

Write your daemon to be a daemon, and not to care
about TTYs at all. Provide a well-defined IPC
interface via signals, a FIFO, a Unix socket,
an IP socket, shared memory, or whatever.
