USB 3G/4G Sticks - How to get Info?

[jmone]

I don't see any info in the Merlin GUI on info like Signal Strength / Quality / Band etc of the USB Modems when plugged in. Is there are way of getting this info (even via Telnet etc)?
Thanks

Been a long time - but there are standard AT commands that one can use to query the modem in the 3G/4G device -

Thanks (this brings back memory of the old modem days...) Anyway, how do you issue AT Commands from Telnet on these Routers to the USB Stick?

so one might have to use Minicom perhaps - try setting it for 115200 8-n-1 and see where it takes you...

Not telnet - that's for IP based hosts...

Thanks - I had tried to run from a Telnet session but I don't think it is install (or am I doing this all wrong)?

FYI doing a "sysinfo" shows some info under "USB Devices" but nothing on the modem stats
