I am using this thread to help send commands to an 841.  I can SSH in and send the below command:

cgminer --lowmem --avalon8-fan 40-100 --avalon8-voltage-level-offset 0 {REDACTED POOL} --api-allow W:0/0 --api-listen --avalon8-voltage-level 0 --avalon8-voltage-level-offset 0 --real-quiet

The only way this works is if I first stop the cgminer (/etc/init.d/cgminer stop) and then send the above command.  The problem is after that it seems that I am locked out from stopping or sending new commands (for instance, set voltage level 1 with the above command with modifier). 

It seems that I am shutting down the default running cgminer and then starting a new one.  Is this correct?  Is there a better way to be able to toggle? 

Thanks in advance

When I try to update the Firmware I get "The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform."

I have tried the S9 fixer firmware, Awesome Miner, and latest S9.  It seems that BRAIINS has it locked.

Any help would be appreciated.

Thanks

We have a need to shed load when demanded by the power producer.  Short of just "pulling the cord", it seemed that we could drop the connection to the S9 and it would idle; however, our power monitor still shows full load.  Any ideas on how to throttle down on demand (a script would be great)?

Thanks
