[Bluez-devel] DUND features

   I have read the Bluetooth DUN specifications, and it appears that
devices supporting DUN are supposed to implement a set of AT-compatible
commands in order to fully support this profile: so far it does not seem
that DUND is supporting anything in particular.

   When using Palm-compatible devices as clients, this is not a problem
because it is possible to configure them to start PPP link negotiation
independently from link establishment. But in the case of Windows
clients, it creates problems because the Windows computer sends AT
commands and tries to dial a number to connect to the Linux server
offering DUN...

   Are there plans to correct this at the moment? Alternatively, are
there known workarounds to enable windows-based clients to connect to
Linux servers running dund ? Apparently the option called "msdun" is not
enough...

Regards,

Edouard

there is a difference between the DUN and LAN profile on the server side
even if our program for LAN access using PPP is called dund. For the DUN
profile you need a modem emulation (the AT command parser) on the server
side.
