on_sub_option Event

Fired when a Telnet SubOption command comes from the Telnet server.


class TelnetSubOptionEventParams(object):
  def sub_option() -> bytes: ...

# In class Telnet:
def on_sub_option() -> Callable[[TelnetSubOptionEventParams], None]: ...
def on_sub_option(event_hook: Callable[[TelnetSubOptionEventParams], None]) -> None: ...


The SubOption parameter contains the suboption data as sent by the other end. The enclosing suboption command codes are stripped away.
