I agree - very good. VPN over MB routing now works correctly too!

I still have one issue with the modem init string. I'd like to recommend it be extended to the following:

\rAT&F E0 V1 X4 &C1 +FCLASS=0 +CREG=0

Rationale is as follows:

I have a particular problem with a soft modem on a Palm handheld. It often needs an initial <CR> before it responds. I think it's probably because a garbage character is sent when the USB connection is opened, and AT has to appear at the start of a line. It only exhibits the problem on Linux, not on Windows, which make me think it's interfacing, not the software. It could happen to any device, and the initial <CR> should not adversely affect anything.

AT&F is slightly more reliable than ATZ, as it restores to factory defaults. The latter restores to the last settings saved with AT&W, and may not even be implemented.

In later exchanges, NM matches responses assuming the CREG mode of the modem is 0. If it's not then the initialisation will fail. Although most modems default to CREG=0 it's not mandatory, and the initial value may be different (my soft modem defaults to CREG=1). +CREG=0 in the initialisation ensures the correct mode.

I've worked round this by binary patching NetworkManager after installing it, but that's not much of a long-term solution :-/. I raised these issues before, though not quite so coherently - I suspect they got buried.

Would the NM team be able to implement this?
