Hi!
I have a problem with laptops:
I already used the same procedure as you on different desktop-PCs with a Nokia 3650 and it did work,
but on te two laptops wich i tried (Asus L3000D and Acer TM 345T) it did not work completely: it starts correctly but after a while it hangs.
I don't think it is a problem of lcp-echo, because I commented out the two lines lcp-echo####, it seems like the problem affected the communication through the usb with the bluetooth device (chip CSR, a Roper ROBTC2-USB), and after it hangs, the GPRS connection on the phone still remains on, and if I try to restart GPRS connection, PPPD restarts, but it does not even try to re-establish the GPRS connection.
I hope you or someone else on the forum still had and solved this problem, but I did not found any solution with the search feature of the site.
