USSD - How can i simulate a Hang-up pressing button?

[wiros]

Hi, i´m wondering someone know, how can i simulate with AT commands a hang-up event phone using a communication USSD?. I have an application that exchange USSD codes with a remote service, and now i´m facing a problem with this service, and the easiest way to resolve this problem is sending a hangup event from my modem (using at commands). I´m using pyserial to implement this software and i send messages using this command: AT+CUSD . Can anyone help me?

The AT command set is extremely well documented.

H0 is a hang up.

H0 is a hang up.

ATH0 hangs up a dial-up connection, but OP is using USSD not dial-up.
I send AT+CUSD=2 to cancel a USSD session.

Ok, AT+CUSD=2, it works for me. Thanks!
