>Description:
        The ppp from pkgsrc doesn't connect to isdnd. It claims:
        Warning: deflink: tcsetattr: Failed configuring device
        The ppp from awfulhak connects to isdnd. However I was not able to
        setup channel bundling.

        ppp.conf is:

default:
 set socket /var/run/pppctl ""
 set log Phase Chat LCP IPCP CCP tun command
 set device /dev/isdnbchan0 /dev/isdnbchan1

 set filter alive  0 deny udp dst eq 137
 set filter alive  1 deny udp dst eq 138
 set filter alive  2 deny udp dst eq 139
 set filter alive  3 deny tcp dst eq 137
 set filter alive  4 deny tcp dst eq 80
 set filter alive  5 deny 50
 set filter alive  6 permit MYADDR 0/0
 set filter alive  7 permit 0/0 MYADDR tcp estab
 set filter alive  8 deny 0/0 MYADDR icmp       # Ping to us from outside
 set filter alive  9 deny 0/0 0/0

    set filter dial 0 deny tcp finrst              # Badly closed TCP channels
    set filter dial 1 permit 0 0

 set log local +Chat Connect IPCP LCP Phase
 allow user u

bluewin:
 set cd 20
 set phone 10
 set login
 set authname name
 set authkey key
 set timeout 178
 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.252 0.0.0.0
 add default HISADDR
 set mode auto


Normalized log from pkgsrc ppp looks like:

>How-To-Repeat:
        Start one or the other ppp with `-auto entry', use '
        pppctl /var/run/pppctl' and issue 'dial'.
>Fix:
        The ppp from awfulhak connects to isdnd. However I was not able to
        setup channel bundling.
