Problem software says error wrong com Port.
But the K-Line interface is on com port 1
any one now the problem?

i found the fault the 4D emulator software need a USB to serial interface with k-line.
I used the computer's internal serial com port with a Kline adapter that the software does not recognize

That happens.
Not a fault in software, problem is with your hardware drivers, hardware conflicts or hardware itself.
Standard baud rates used here, nothing exceptional.

Hello,

resp: 00000000
these are the key data that I enter directly.

Key 0000000000 ?
Seriously?

I have a tool to read the key and it told me that

P4 (KEY PASSWORD) is write only, it is not readable using standard transponder machines.
Although it can be calculated...
