Sadly, none of the above worked. Not AT&F, not ATE1, not ATQ0, not AT&FE1Q0. Interestingly, on one of the modems, if I send an ATDT command, I actually see the OH light (Off Hook) turn on for a little while. But I can't get any response codes from the darn things.
I suppose it's possible that they've just plain failed... but it's still weird that two different models failed in pretty much the same way.
