I have imported a T1 driver into NetBSD-current. It is for the
RISCom N2 PCI card, or SDL Communications. It should have made it
into the latest sup. I don't have access to the ISA flavor of the card.
It isn't perfect, and needs cleanup, but I think it is stable. I used
it on 1.2G for several months under pretty heavy use and had no problems
with it. I'd appreciate a note if you try it, and what success you had.
I currently have no way to test this under -current, however. If anyone
wants to test it, add the following to your kernel config file:
ntwoc* at pci? dev ? function ? # SDL Comm N2 PCI card
and rebuild your kernel.
The card will come up as ntwo0 and (if you have two ports on it) ntwo1.
It will do Cisco-HDLC only, presently, and will answer but not generate
keepalive packets. This is enough to make a Cisco, FreeBSD, or BSDI box
I'd like to design and implement a generic point-to-point framework where
any protocol can be selected for any serial line, probably only for
synchronous lines (HSSI, T1, DS3, etc) at first.
I can, of course, write the cisco-hdlc portion. Anyone want to help and
form the PPP portion? Or, better yet, frame relay?
