These cards seem to be compatible with European ISDN standards. However, I do not know whether these are compatible with Austrian telecom standards (but I guess I could look it up; somebody around here should know.) On the other hand, there are some external, so called ISDN modems, which talk to the computer via RS-232 and answer to the Hayes compatible modem command set. These go up to 115 k async. Thirdly, ether to ISDN bridges also exist. > Same question for X25.

I don't know for sure, but I think I've seen something about X.25 in the kernel sources. Didn't investigate it, though, as I have absolutely no use for it. > If somebody has info about drivers, stability, protocls, and/or can point > me where to find ? > Also I would like to ask, under which conditions we can use this system > commercially.

Parts of the kernel are licensed to the user under two, different, licenses. Most of the kernel is under Berkeley style copyright/license which allows you to do whatever you wish with those parts, as long as you give credit to the original authors. You can sell the binaries only, you can incorpo- rate sources into your own products, etc. Some other parts, unfortunately also the drivers for Dr. Neuhaus cards, are under GNU General Public License. This one requires that you give away the source to the derived program (in this case the kernel as a whole) if it uses parts of GPL licensed code, in the case that the derived program is distributed. This means that you cannot really sell binaries only, and you cannot sell/distribute even parts of the system which are binary only (proprietary drivers, for instance.) You can use them as you wish for your own purposes, however. As far as I know, there are no parts of the system that prevent the use of it in commercial environment. Some ported applications (ports, not packages) may have such restrictions. These applications are, within the framework of FreeBSD, distributed only as patches to the original distributions, and are not packaged (neither as binaries, nor sources.) > Which are the suggested Pci Ehtercards, are they stable enough ? Drivers for cards based on Digital chips are excellent. These come in 10Mbps and 100Mbps varieties. > Please mail also directly, cause I am not on the list. > Thanks for Your help, anton Hope it helps, /Alby > PS: I just started to use 2.0.5 privatly, and like to say its GREAT work.
