It's not too likely that Twisted's telnet implementation and telnet(1) negotiate exactly the same features right out of the box. If you figure out what telnet(1) and this switch are negotiating then it will probably be fairly straightforward to convince your Twisted code to behave the same way (application-controllable feature negotiation is one of the main features of twisted.conch.telnet). > > Peter. > _______________________________________________ > Twisted mailing list -- [email protected] > To unsubscribe send an email to [email protected] > https://mail.python.org/mailman3/lists/twisted.python.org/ > Message archived at > https://mail.python.org/archives/list/[email protected]/message/P4YLAR6GXSEMD3C2HPEVMNI6OXMXNDSY/ > Code of Conduct: https://twisted.org/conduct >
