Just an update - problem solved.   I couldn't find anything in my system log 
files so I asked on the Debian-user list and got a reply 'Maybe MTU 
problem?'  (which is about as cryptic as one could get).
So after I found out what a MTU is   8)    and fiddled with the line 'mtu <n>' 
in my /etc/ppp/options  it now all works perfectly!!!
(mtu 1024 improved things but not complete cure,  mtu 512 is the answer in my 
case).

(..."Maximum Transmission Unit" -  roughly = 'packet size')
