All you have to is the drop the funny business at the end with slashes on the COM port.  This worked for me

cgminer.exe -o stratum+tcp://us-east.rapidhash.net:3333 -u FURY -p PASS --nocheck-golden --chips-count 6 --ltc-clk 328 -S COM4


If that doesn't work, let me know and I'll help you out the best I can.


I accept tips!
