3g dongle connected via ppp daemon unable to send AT commnads to the dongle
I have connected a 3g USB dongle to my system and is able to get data connectivity using ppp protocol, but due to my requirement I also need to send messages via the dongle but I am unable to send the AT commands to it, as it is not responding. But when I disconnect the data connectivity I am able to send sms and again, I have to connect for net and this process continues.
Is there any way to send sms(or any AT commands) even while the data connection is on?? I have searched a lot but haven't got any meaningful solutions. |
AFAIU, some of these broadband modem devices present more than one tty interface - one for data, and one for control etc. For example, my own device shows up with 3
Code:
ls -l /dev/ttyUSB* |

And on USB1 I am getting only: AT OK other than that no other AT commands are working. |
