Probably not, since *everything* comes with Windows install floppies or
CDs. But really, who knows? The best way to find out is to look up the
device on 3Com's Web site (or perhaps USR's), or do a Google search ...
things you can do as readily as we can.

This mainly depends on what your ISP says. PPP over ISDN is one way to do
it ... certainly the most likely. I've also (many years ago) used hardware
bridges that connected to ISDN on the external side, Ethernet on the
internal side. Other options are possible in principle, but not
straightforward if the ISDN device looks like a modem to the PC.
Assuming ppp ... your external interface will be ppp0, and pppd will need
to know to use /dev/ttyS0 (or S1, depending on which serial port you
connect to) to establish that interface.

Some did. Again, you'll need to check about yours specifically.

The likely answer is no. Since the ISDN device connects to a serial port,
Linux should need to know nothing special about it, just its modem-like
things (e.g., speed, dialing).

This isn't really a question, and I don't know what the statement means. I
just did a Google search on "isdn 3Com Impact IQ linux" and got a bunch of
hits. From the listings on the search-results page, the first few looked
helpful (though I didn't go on to read the actual links, figuring that you
can do that as easily as, and more productively than, I).
