how i can change negotiation commnds

[MohammedTayeh1993]

this is my python code to connect server

HOST = 'my server ip' # Symbolic name, meaning all available interfaces
PORT = 23
import socket
s = socket.socket()
#Connecting using telnet
s.connect((HOST,23))
a = s.recv(100000)
print(str(a))

this print result is
b'\xff\xfb\x01'
how i can change it to other from server code
