Hi Marcel,
There is an option --dialup -u (Pretend to be a dialup/telephone) in the dund daemon. But I see that this option only registers a DIALUP_NET_SVCLASS_ID SDP record. It does nothing else apart from that. My requirement is that I want to make dund work as a DUN Gateway. Thus, it should read AT commands sent from the DUN Terminal and send back responses to it.
Is there some way through which I can make dund do so?
Best Regards,
Mayank

Yes, I think this is what I need. I'll try this out.

Hi,
I don't know if you can make dund work like this, however, the patch I =
just proposed can be used in a similar way :
See thread called "[Bluez-devel] rfcomm patch to startup an executable =
at connection"
If a modem is installed on a serial port, then a simple gateway =
application can be used between /dev/rfcomm0 and the modem.
1) Create SDP record:
sdptool add --channel 20 DUN
2) setup your serial port
stty -F /dev/ttyS0 115200 ...
3) Start the rfcomm utility in watch mode:
rfcomm --raw watch 0 20 gateway_app {} /dev/ttyS0
Note: the {} will be replaced by /dev/rfcomm0.
4) Setup your DUN data terminal and connect.
Upon connection, rfcomm launches a gateway_app process.
It's up to you to write the gateway ;) Something like this should be enough:
int f1 =3D open(argv[1]);
int f2 =3D open(argv[2]);
while(!error)
{
int fd =3D poll(f1, f2)
if(fd=3D=3D1)
read(f1); write(f2);
else if(fd=3D=3D2)
read(f2); write(f1);
else error;
}
close(f1);
close(f2);
Maybe a shell command already exists
Hope this helps!
