Under Windows XP, tried to use SnoopyPro to capture AT
commands issued by an dialer, GPRSManager, to a
Motorola E680 cellphone modem through the USB4 port.
When SP installed and started on the port, the program
failed to make a connection to the modem, and
thereafter could not reboot XP except by choosing the
Boot with Last Good Settings option.
A sniffer that prevents the function it is supposed to
monitor and crashes the operating system needs more work.
