Tell me, the Huawei 171 modem was defined as: / dev / sr1 in the Ubuntu operating system. I changed the serial port setting in minicom, entered the minicom console, but he does not want to enter the AT command. The cursor is not flashing and no letters are entered. Maybe I'm doing something wrong, help me figure it out.
UPDATE
How to do that the modem is defined as a usb device. The usb-modeswitch program is installed. Disconnected the modem, pulled out the SIM card, inserted the modem into usb and displays a window, the disk cannot be mounted, then a lot of text is in English, where / dev / sr1 was written. Maybe you need to register something in the terminal? I have a version of Ubuntu 14.04
