Your case such as the previous two issues to some users who tried to help them in another forum and the same problem and test the rs 232 after it became clear that it was worked, but in the last two were both related to their problem from motherboard, I hope your problem not from motherboard.
But the problem is you can not connect pc to your box...
If as you said earlier:
1-You test rc 232 and worked well.
2-Your wire lan and null modem cable fine.
3-You have tried with 2 pc.
4-You have tried another power supply.
5-All version dream up, optiflasher, No CA Found software and also Hyper terminal does not connected to box.
So tell me the problem from where you think? if not from motherboard then from where?
