Hello Forum,
Our customer locates all 5 seconds BROADCASTS over Ethernet. The BROADCASTS includes the information ("F&S-Systeme GmbH" und "PICOCOM1"). Why is it necessary? How can I disable it?
Best regards

How disable BROADCAST over Ethernet?

Hello,
by default runs a Broadcast Driver (BCS) which offer the possibilty to identiy the device in a Network (e.g. by the F&S tool "FSDevcieSpy"). The broadcast should only send for a adjustable time after boot.
You can influce the drivers behaviour via Registry [HKLM\Drivers\Drivers\Builtin\BCSend]:
BroadcastCount=DWORD:n -> amount of retries (default 20)
BroadcastDelay=DWORD:n -> time between two broadcasts in seconds (defuault 6)
Flags=DWORD:n -> set n to 4 for disable the driver (4=DEVFLAGS_NOLOAD)! (default 16) -
Hello,
the given registry settings under [HKLM\Drivers\Drivers\Builtin\BCSend
- BroadcastCount=DWORD:n -> amount of retries (default 20)
- BroadcastDelay=DWORD:n -> time between two broadcasts in seconds (defuault 6)
- Flags=DWORD:n -> set n to 4 for disable the driver (4=DEVFLAGS_NOLOAD)! (default 16)have no effect to the broadcasts with the information "F&S-Systeme GmbH" und "PICOCOM1".
But we have detected, if we have a connection with CERHOST the broadcasts ends. If we disconnect CERHOST from the PICOCOM, the broadcasts begins again.
What can we do?Information about our KERNEL: V1.18 from Jun 28 2011 (NKPC1_CORE_adaptronic_110628.bin)
Best regards

Hello,
QuoteFlags=DWORD:n -> set n to 4 for disable the driver (4=DEVFLAGS_NOLOAD)! (default 16)
Can you please check from debug output that BCS Driver is not loaded any more in this case.
Did you run cerdisp.exe by default or only on demand. Assume cerdisp.exe sends the broadcasts not BCS! Else cerhost.exe cannot see the board in a Network:).
Tanks.
