ppp0 operstate is unknown, while interface is up


I am using a script to perform the GPRS modem power on function and pppd restart. For that purpose I need to know the operating state of ppp0 in /sys/class/net/ppp0/operstate. But operstate shows to be "unknown" even when the ppp0 interface is up. I want to know the real state of the interface. Any suggestions????
