Heh, I disagree with both of you ;) Winmodems *are* more likely to have a
black sleeve, because the frequencies on board are higher therefore
could do with the shielding. Being BABT approved doesn't mean it needs to
be shielded (the pc case can do that), the shielding is quite often there
not because of the RF output of the thing, but because of the high
voltages involved with the telephone system. That's why you have to
measure out the creep distance between your modem and your other cards
(has anyone here done this? No?).

What's this then? http://www.3com.co.uk/56k/wininchoose.html . I'm happy
to be proved wrong, but I didn't think there was any such bus restriction
on a winmodem?

Isapnp is a good bet. If that doesn't find it, nothing will. Probably, a
good way to check if the modem is a winmodem or not is to send it a hayes
command? I.e., send it 'AT' and you should get the response 'OK'. I don't
know about this (someone will correct me, I'm sure), but I wouldn't think
a winmodem will respond to the hayes command set. If they *do*, I think
that's a rotten design decision ;))
