See, that's what I mean. The modem just goes crazy.

Now, the *logging* of the whole page is mgetty's fault (it's not very
robust to the faulty behaviour of the USR), but the USR completely
violates class 2.0 specifications here.

I tried it about 15 times, and it did always behave exactly the same --
wrong.

Well, you're right, I should stop bashing USR. They *are* making good
modems, very good for data, and good for fax/data mixing, if you don't
want to have a real perfect fax implementation and have no need for fax
poll serving.
