QExtSerialPort with AT commands

[Althor]

Hi,

I´m trying QExtSerialPort (QEspTest) with an usb modem which I send at commands to. AT Commands I write to the usb modem are delivered succesfully, but when I push the receive button I get always no bytes available message.

I never get any answer from the usb modem though it executes the at commands.

Can you help me?

Thanks in advance.
Regards.

Don´t answer this question.

I´ve solved it already. I must include \r\n at the end of the at command.
