Uart HL7692 modem conection

i have to make a conection through uart1_main with dev kit airprime. Due to, i make a dial up on windows 10 setting the modem via com 5 set by the pc.
i am not able to connect via uart1_main to pc, so there are some default configuration or some configuration that i have to set for this?

I try to connect the modem dialing up but i encountered error 639 hardware error.
By the way when i connect uart with teraterm i can put at command without problems.

somebody can help?

Hi Meydey,

Before PPP dial up in win10, make sure network registered.
And make sure the baud rate set 115200 as below:
