[Twisted-Python] Screen clearing in the Manhole

[Peter Westlake]

I'm making a manhole service in the usual way:

class PF(ServerProtocol):        def protocolFactory(*a, **kw):
return manhole.Manhole(namespace)

realm = manhole_ssh.TerminalRealm()    realm.chainedProtocolFactory = PF
mh_portal = portal.Portal(realm)    mh_portal.registerChecker(checker)

manhole_service = TCPServer(0, manhole_ssh.ConchFactory(mh_portal))
manhole_service.startService()

and I'd like to print a message when the terminal is opened. This
change does it:

class PF(ServerProtocol):        def protocolFactory(*a, **kw):
class Manhole(manhole.Manhole):                def connectionMade(self):
super(Manhole, self).connectionMade()
self.terminal.write('Hello')            return
manhole.Manhole(namespace)

and so does this version, which is better because
t.c.i.i.ServerProtocol.connectionMade says it is the place to
write messages:

class PF(ServerProtocol):        def protocolFactory(*a, **kw):
return manhole.Manhole(namespace)

def connectionMade(self):            ServerProtocol.connectionMade(self)
self.write('Hello')

But in both cases, after the message the screen is cleared by what looks
like a form feed, and another prompt is printed. So far I can't find
where in the code this happens. Is there a way to print a message and
not have it scrolled off the screen?

Thanks,

Peter.
