hello guys

one question, i'd like to set the stratum difficulty manually on my miners to 20 shares per minute as suggested in https://bitcointalk.org/index.php?topic=274023.0

i did this on my Avalon6 controller without problems using the "--suggest-diff" command on the cgminer "more options" field available in the Avalon6 controller interface.

however i got a few Antminer s7, s4 and s5 that do not offer any field to enter any extra cgminer commands, anybody know how do i set the stratum difficulty manually on Antminers?

thanks in advance for any information
