Line feed doesn't work in C# (socket), why?

Question

C++ / C#

Good afternoon. There is this code:

string cmd = "admin" + "\n";
byte[] buf = System.Text.ASCIIEncoding.ASCII.GetBytes(cmd.Replace("\0xFF", "\0xFF\0xFF"));
tcpSocket.GetStream().Write(buf, 0, buf.Length);

These are the lines from the telnet client that opens is implemented on sockets. The problem is that the cmd text, line feed character (10) gets into the console, but it does not work. Simply put, do not "press Enter" at the end of the input.
Tried different combinations with \r, no difference....
On the other side of UNIX.
Thank you!
