Someone is sending you a remote modem commant to hang up.. That command is ATH0

     There are programs which send this command provided they know the IP address of your buddy.

  Have a look at this article which will explain you in detail about the hang up ping.

Capture some evidence...

1)  Go to http://www.ethereal.com/download.html
2)  Under Windows 98/ME/2000/XP/2003 Installers, select a site near you
3)  Download WinPcap_3_0.exe and ethereal-setup-0.10.4.exe
4)  Install WinPcap_3_0 - double click on the WinPcap_3_0.exe file, just
click OK / Yes throughout
5)  Install ethereal-setup-0.10.4 - double click on the file, accept all the
defaults (OK / Yes throughout)
6)  Start the Ethereal application
7)  Go to Capture > Start
8)  Under Interface, select your Internet facing interface.  If you're
unsure, then select one, and continue.  If it displays results, then you've
got the right interface, if your capture is empty, then select another
interface and carry on...
9)  Under Capture Files, put \capture.cap
10)  Click OK
11)  Capturing will commence....
12)  Capture what you need to
13) Go back to Ethereal, click Stop
14)  Analyse the c:\capture.cap file, or send it to me - tim_holman@hotmail.com
