But i try have comunication only for  the serial port with Modbus Poll, Only use rs232, but i haven´t comunication, i used 9600 baud,8 data bist, none parity 1 stop bit and slave id 1 since address 0

The genmon project from the github link above has very good documentation, but there's a lot of it. The 8-pin aux connector uses true RS-232 levels so you may need to convert to TTL for your application. Pinout:
2 - common ground
7 - Controller receive data (data from your device to controller)
8 - Controller transmit data (data from controller to your device)

9600 baud, N-8-1
Modbus address 9d

Set the modbus address you're polling to 9d hex.
