I am running Debian on an Embedded system and am trying to use minicom to periodically get the signal strength of my USB EVDO modem using the AT+CSQ command.
When the modem is not connected, I can simply use minicom to connect to the port and execute this command. However, when the modem connects to the network, commands in minicom no longer work (ie. nothing happens or is echoed to the screen).
Any assistance with obtaining the signal strength while connected is appreciated.
