I have this external ISDN box (Teles-BRI/2TR) that plugs into the
parallell port. I don't think it does modem emulation, but since it
probably uses the same chipset as the internal Teles cards (HiSAX) it
sholdn't be that difficult to write a driver.
Has anyone already written a driver (I checked the ISDN4Linux pages,
but I couldn't find anything) or at least have some more information
besides what comes with the box when you buy it?
