Hi! Thanks for this PR!

This looks good, but seems to borrow much of the construction of the Dell-X model. Is there any fundamental incompatibility that would prevent extending the Dell-X model to also support the Dell-N?

[wasapi]

The main incompatibility is the match of "More:" in the dellx model; for N-Series it must match "--More--". Also, I find it more elegant to add a 'post_login' to disable page view, but I don't know if it works with X-Series.

Hello, I have a Dell N-2048 switch (running image version 6.6.0.10) and I'm using the powerconnect model, it works pretty good. The only problem is it doesn't retrieve the output of the 'show system' command which is fine for me and also the code of the dellx model I think whould have the same problem.

[wasapi]

I didn't take a look at the powerconnect model because the powerconnect 2848 switchs I replaced had almost nothing in the cli, except a show tech-support command. Indeed it seem it can work with N-Series. But N-Series commands are the same as the X-Series, except the more text, it could be nice if someone could test the post_login 'terminal length 0' instead of the expect block, I think it should work. Maybe it should be better if I directly made a pull request for the dellx model.

Sadly I'm still getting the follow return from a PowerConnect switch using this, another modified file I found, and the original file. It is interesting that it runs the first command no issue, then the second command runs but it only returns the last 4ish lines of a much larger output in the cli.
