I think just 2006-era modems and some old phones would get confused,
and we C&P-ed that everywhere.  If we want to speed up probing a bit,
we could remove that for sane plugins.  We don't want to remove that
for the more esoteric ones (anydata, iridium(?), motorola, pantech) and
also for Huawei/ZTE which still support really old stuff.

For Samsung and HSO, we can definitely set to 0 and test it.  I have
both Samsung modems and a bunch of HSOs, so no problem there.
