Hello ,

    I just met a problem that when dialup user disconnects
his/her line(modem for example). the remote pppd detected
this and make a account request to Radius server, some information
such as calling number and called number are included in 
this request message. calling number, for example, is retrieved
by calling ioctl() on /dev/ttyxxxx. if disconnect the line directly,
ioctl() return nothing;  if logoff from application, ioctl() return 
the calling number correctly. 
    can anybody give some explanation on this and is there any
way to solve ?

Thanks,
YK
