yes, the TE mode works in your case. At least for a year or so
until the Deutsche Telekom will cancel your ISDN line :o)

Your analysis regarding the CAPI library is also correct,
you need the one supplied by isdn4-utils.

When I run "strace capiinfo", it first checks for /dev/capi20
and then opens the mISDNuserd socket in /var/run/mISDNcapid/sock:

open("/dev/capi20", O_RDWR)             = 4
ioctl(4, CAPI_INSTALLED, 0)             = -1 ENXIO (No such device or address)
socket(PF_FILE, SOCK_SEQPACKET, 0)      = 5
connect(5, {sa_family=AF_FILE, path="/var/run/mISDNcapid/sock"}, 110) = 0

Cheers,
Thomas
