Sharing makes the Powerball forums @BiqaLi
pcrf\pc programlar\pcrf (pc) folder in which to copy the file into c:\windows\system32 called mscomm32. then
We run the program called pcrf, and we select our cards to the appropriate attribute from the seçenğini the screen warning saying yes to com1 of the circuit we wanted to establish a remote connection with the computer
There are two LEDs on the card any energy verdğimizde Yates
When we say yes while the other led and computer connectivity with means provided
then the pc programindan 1/0 konumlarina bringing you can pull the relays.
