For legacy use, Modem port must be enabled in configurations modules:

example, USBCOMP = 6, or 8

 

 

 

Test screen my Sierra Wireless EM7305:

Hi Skvo

Would you please provide more explanation about this:

On screen You show this parameter but how I can change it?

What file or console what command?

 

I have also this modem EM7305 and USB and WWAN recognize but no modem software or network.

Post #1 clearly shows that you use good old AT commands (old Modem control facility) to enable the module's modem port. This is done through direct access to the WWAN module, i.e. through a serial connection to the USB port using tools such as Terminal, Putty or Screen (which you just call from Terminal) as illustrated on post #1. List your modem device(s) with line command:

ls /dev/tty

 

You can Google for "AT commands" if you've never encountered them. It's kind of old stuff and only old farts and network/telecom people tend to know about them these days...  To obtain EM7305 AT commands complete references, Google for "EM7305 AT commands"...

 

Going back to the screenshot of post #1, you can see several such AT commands:

1) ati

-> returns information about the device

 

2) at!udusbcomp?

-> queries the modem about current/active mode

 

3) at!udusbcomp=?

-> queries the modem about the list various values that can be used to assign its mode

 

So, if you wanted to set USBCOMP to 6, you would then issue the command at!udusbcomp=6. When you 1st connect to the modem, you can check it responds properly by issuing the basic at command. Modem should reply by an Ok message.
