new I4B driver v.1.5.2

[hselasky at c2i.net (Hans Petter Selasky)]

Hi,

There is a new version (1.5.2) of I4B available from:
http://home.c2i.net/hselasky/isdn4bsd/privat/temporary/

It should compile with FreeBSD-5-current and older versions of FreeBSD-5.

USB-ISDN support has been disabled until a new USB interface is in place.
But you can get USB-ISDN devices working using version 1.5.0 with
FreeBSD-5.1 or FreeBSD-5.2, but not FreeBSD-5-current.

Some plans for the future:
 - support for more than 3*2 channels
 - support for VoIP

I suggest that we do a job getting the ISDN-hardware that is not
supported by this I4B release, but is supported by FreeBSD-5-current,
into the new Layer1 and Layer4, and then get it committed to 
FreeBSD-5-current?

I have now been using this driver for some months and I have seen very few 
bugs. I have seen no bugs in Layer1, Layer2, Layer3, Layer4 and isdnd which 
was rewritten.

currently unresolved bug: ppp can go into a loop dialing out and hanging up, 
if the "down" command has been used, but usually recovers after a few dials. 
Hence ppp does not get any signals back from /dev/i4brbc about the dial-state, 
that should be a bug in ppp?

Any comments?

Yours
