Hello world,
Using a GPRS modem I am able to establish a GPRS connection.
When the GPRS connection goes down, I want to run some executables from a script.
How can I verify the status of the PPP connection? Is there any option which I can utilise to do neccessary action when the ppp connection goes down?

You should be able to see your ppp information by ifconfig.

Hi Sonic,
By issuing the ifconfig command, I can see the status of the PPP connection status. This way,I need to poll everytime.
But I need to automate the execution when the PPP connection goes down,

If the delay between ppp is down and you detection is not critical. You can check every 5 seconds, which won't consume too much cpu power.

You may also check if hotplug can help.

Hi Sonic,
Detecting ppp connection is not very critical!
How can I use the timers from the userspace? There are many timers available. But confused to choose which one to be used.
Can I use kernel timers from the user space? I went through the following document too.
docs.blackfin.uclinux.org/doku.php?id=linux-kernel:timers
Could you please let me know what are the hotplugs?

You can use enable drivers/char/bfin_simple_timer.c and control the generic timer on blacfin via ioctl interface.
As to hotplug framework in Linux, refer to linux-hotplug.sourceforge.net/

use ifplugd. busybox should already support it.
