I was using a wireless net card. the card connect to pc through USB. when it's connected, the usb is probed as two devices: one is ftdi,the other is cdc-acm.

I can use it to make one call. when I use it to make another call while hold the first call. the application cann't get the wright At respond.

it's like this (I cann't remeber the exact form):
AT+CLCC "10086"
AT+CLCC "1360000000" OK

the problem is I cann't receive :AT+CLCC "1360000000" OK.
but in the log from the card, it had sent it out.

This Problem has been fixed. when we use
we get the two strings which is separated by NULL. In our
application, the following chars are discarded. So they missed the second string
