So it seems incompatible to start with, where the alu* scripts might not entirely work with every command on the OS6000 that I have, but most of them are accepted in older (legacy) components but also on the newer

I'm told that these are totally separate from the Nokia systems I know and

I suspect that the login script it out of sync (ahead of) the cli.  possibly
due to incorrectly matching a rogue prompt in some output or banner.
