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?
Cheers, Rick
