I'm trying to write a small program in C# to control my TV and am having problems logging into it. I set my username and password on the tv and have connected to the IP and port.

When I send a message, I get a reply that says "Login:"
I try to send it my username and wait for an ok, but it hangs.
My username is "admin" so I've tried sending "admin" or "admin " with 3 spaces to make 8 bytes but the result is the same.

I've tried sending my username, wait for the "login:" reply, then sending my password but it hangs again.

How is everyone else sending their username/password to connect?

Thanks in advance!
