Now, I'm trying to communicate with USB modem (3G dongle) by CDC_Serial example project which I found in "Freescale MQX 3.8/usb/host/examples/cdc/".
Everything look very well, I can send AT-Commands to query and get their reply correctly.
Until when I dial to GPRS by the command "ATDT*99***1#", Which I expect to receive "CONNECT" response.
But, I never gotten this reply, The modem just switch to data mode and don't accept command till reset.
Has someone give me an advise this problem, Please?
