i can log into my usb 3g modem with command in the terminal:

/system serial-terminal port=usb2 channel=1 ;              

[Ctrl-A is the prefix key]

*EMRDY: 1

and than with AT command
AT*E2OTR?
result
*E2OTR: 0,75,80,85,1,43
last number is the temeperature

OK

how to obtain *E2OTR: 0,75,80,85,1,43 with a script? i need to put the last number 43 into a variable for monitoring, please help… thank you

I need some solution.
Is it possible - send AT-commands from script and analyze answers?
