Yes! It was my phone's way of telling me that whatever I was sending, it was not what it was expecting, echoing back the same information. So, I experimented with the relevant /etc/ppp/ip-up.d/45-mySIP_connect.sh by removing all entries but this: #!/bin/sh exec /usr/sbin/chat -v '' ATZ OK ATDT*99# CONNECT '' It now works! :-) ================================================================= Dec 6 12:40:21 pppd[5644]: pppd 2.4.5 started by michael, uid 0 Dec 6 12:40:21 chat[5647]: send (ATZ^M) Dec 6 12:40:21 chat[5647]: expect (OK) Dec 6 12:40:21 chat[5647]: ATZ^M^M Dec 6 12:40:21 chat[5647]: OK Dec 6 12:40:21 chat[5647]: -- got it Dec 6 12:40:21 chat[5647]: send (ATDT*99#^M) Dec 6 12:40:21 chat[5647]: expect (CONNECT) Dec 6 12:40:21 chat[5647]: ^M Dec 6 12:40:23 chat[5647]: ATDT*99#^M^M Dec 6 12:40:23 chat[5647]: CONNECT Dec 6 12:40:23 chat[5647]: -- got it Dec 6 12:40:23 chat[5647]: send (^M) Dec 6 12:40:23 pppd[5644]: Serial connection established.

I suspect something to do with certain characters that need to be escaped in the terminal by bash? Grateful for any pointers. Otherwise, kppp still hangs being able to complete the connection. I have not been able to troublshoot that further. -- Regards, Mick
