I have just tried the same connection with user ppp in multi-link mode and
it seem to be working except the connection hamgs up often and redials with the
following errors in the ppp.log:

Jul 26 02:34:15 dns ppp[269]: tun0: Phase: 1: HDLC errors -> FCS: 1, ADDR: 0, COMD: 0, PROTO: 0 
Jul 26 02:34:17 dns ppp[269]: tun0: Phase: 2: HDLC errors -> FCS: 1, ADDR: 0, COMD: 0, PROTO: 0 

Here is my config:


-------------------------------

default:
 set log Phase Chat Connect LCP IPCP CCP tun command
 set device /dev/cue7 /dev/cuaa0
 set speed 57600
 set phone "0392590000"
 deny lqr
 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"
 set login
 set authname aickin
 set authkey "<SNIP>"
 set timeout 600
 set ifaddr 10.0.0.1/0 10.0.0.2/0 0.0.0.0 0.0.0.0
 add default HISADDR
 set mrru 1500
 clone 1,2
 link 1,2 set mode ddial
-------------------------

Does that look about right or have I missed something essential?

- Ernie.
