Hi,
Please check http://www.developershome.com/sms/smsIntro.asp for a tutorial
on AT commands and SMS.
USB0: Header USB driver
USB1: Serial port 1 from USB driver
USB2: Serial port 2 from USB driver
You should issue AT commands to USB1 & USB2, not USB0.
BR,
Nikos

HI. I recently acquired a usb modem Huawei e1756.
This works fine.
I am learning about of this world. I need to develop a personal software
for SMS, and do what the modem allows. By example, I need read the
signal quality.
Can anyone help me get the commands reference for this modem?,
to send commands to this and receive xxxx, anything...
I have been working an reading:
