The status updates from the second port are prefixed with a caret and are of these forms:
^MODE:3,2 indicates GPRS
^MODE:3,3 indicates EDGE
^MODE:5,4 indicates 3G
^MODE:5,5 indicates HSDPA
^DSFLOWRPT:n,n,n,n,n,n,n
n1 is the duration of the connection in seconds
n2 is transmit (upload) speed in bytes per second (n2 *8 / 1000 will give you kbps)
n3 is receive (download) speed in bytes per second (n3 *8 / 1000 will give you kbps)
n4 is the total bytes transmitted during this session
n5 is the total bytes transmitted during this session
n6 no idea, but I always get 0x1F40 (8000) here
n7 no idea, but I always get 0x7530 (30000) here
You can reset the connection statistics by sending AT^DSFLOWCLR.
---
If anyone is interested, sending DTMF signals in modem-mode (+FCLASS=0) is possible. But it is device-dependent feature.
For Huawei E1550 it is AT^DTMF=<n> command.
----
AT^CVOICE=0 Enable Voice
AT^CVOICE=1 Disable Voice
AT^CVOICE=? Check status
AT^CVOICE? [len=10]
[len=0]
<LF>^CVOICE:0,8000,16,20 [len=21] This answer tells you voice parameters (8 khz,16 bits, 20 ms)
<LF>
----
That need to be tested but voice activation should work with:
AT^U2DIAG=5
then the modem become 0x12d1:0x140c a flash drive.
then I plug in on my Linux Ubuntu computer, use minicom and type AT^U2DIAG=0 to deactivate the damn flash drive.
Maybe it's better to first type AT^U2DIAG=0 and then AT^U2DIAG=5 ...

A = is to verify if locked or unlocked
