# Connect to host with 10 seconds timeout
session.connect("tn3270://localhost:3270",10)

# Show connection state.
print("Cstate: " + str(session.cstate))
print("Width: " + str(session.width))
print("Connected: " + str(session.connected))

# Show cursor position
print(session.cursor)

# Search for string on terminal
