Conduit mLinux: signal strength of 3g Modem

I’d like to monitor the signal strength of my established 3G connection.

I configured pppd to keep the connection alive if it closed by the other side (with the ‘persist’ option) and therefore I also set the option ‘lock’ (maybe unnecessary).

This makes that PPPD is keeping the /dev/modem_at0 open and locked.

With the AT command AT+CSQ I could fetch the information I need. at0 is locked and I tried the following on /dev/modem_at1:

root@mtcdt:~# microcom /dev/modem_at1 
AT+CSQ
+CSQ: 11,2

OK

Is at1 a second serial connection to the modem meant for exactly that?
