While testing ussd-gui I've come across some weird behavior.

1 Is there a way to cancel an action after sending a USSD code? Let's say we've set timeout to 300s, how to cancel the action?
2 Is there a way to terminate ussd-gui while sending a code? I've tried to cancel/close the window, but without a success.
3 Is there a way to implement comments in the ussd-gui config file? For now some lines starting with # are removed, the others get rewritten to the following after sending a USSD code:

%23%20timeout=20
%23timeout=30

4 When exiting by closing the ussd-gui window, I often get segfault:

kernel: ussd-gui[73403] segfault at 7fcff2880e18 ip 00007fcff2880e18 sp 00007fffb8f432c8 error 15 in libQt5Core.so.5.5.1[7fcff2879000+c000]

5 Is there a way to fix the connect/disconnect button. For now it's almost impossible to simply disconnect because it reconnects right away. I think it catches the previous mouse click, and that's why it reconnects after clicking disconnect.

There's a problem with sending USSD codes by pressing enter key on the keyboard. I have to use my mouse instead. Is there a way to fix that issue or am I forced to use the mouse?

ussd-gui has some history of entered USSD codes. Unfortunately, the codes sometimes are complicated and hard to memorize. In modem-manager-gui there was an option to specify a description for each USSD code. Actually, there was an option which allowed to add codes and set their description. Would you add this kind of feature to ussd-gui?

I'm just testing ussd-gui on debian SID, and it works as expected. But there's one thing I can't figure out. Some of the USSD codes have to be answered. In that case, you have to send 0, 1, etc. When I do it via the following AT command:

$ echo -e "AT+CUSD=1,\"*111#\",15\r" >/dev/huawei-E3372-0

I'm able to receive the proper answer and respond to it by sending, for instance 1:

$ echo -e "AT+CUSD=1,\"1\",15\r" >/dev/huawei-E3372-0

After this I get another answer, and so on. Of course, I have to cat the device while sending the AT commands in order to see the results, but generally this works well.

When I want to do the same with ussd-gui, I get an error: Status: ERROR 5: Connection Was Terminated. I wasn't able to respond to any USSD codes. Is this app able to do it?

When you have many USSD codes in favorites, clicking on each and removing them individually is a little bit tiring. Wouldn't be easier to just press the delete key on the keyboard?

It looks like something is wrong when you open ussd-gui and press the connect button when some app is utilizing one of the interface of the modem. For instance, I started gammu-smsd daemon on one interface, and tried to start ussd-gui on the same interface. This always causes an error, because the interface is in use by the first app. So I killed the gammu-smsd daemon and tried to attach ussd-gui to that interface again. Now I got Status: ERROR 5: Unknown Error Has Occured.

There's no way to make it work again. It just gives the error above all the time, even when I reconnect the modem to the USB port. When I cat the device and connect via ussd-gui, I get the following:

ATZ
OK
AT+CUSD=1,"*111*480*3#",15
+CME ERROR: 304
AT+CUSD=2,,15
OK
TZ
OK

So there's ATZ command, the next is the code, but it results with an error.

The only way to fix the modem is by using the following command:

$ echo -e "AT+CMGF=1;^CURC=0;^USSDMODE=0\r" > /dev/huawei-E3372-1

Then ussd-gui works just fine.

You can add two or more entries which are the same. I don't think this should happen. Instead, there should be some notification that would tell you there's a code on the list that you want to add.

Now the SMS button is active when you set the following option in the ussd-gui config file:

source=internal

But when you click the button, you get Status: ERROR 7 .

1 Is there a way to make the ussd-gui windows resizable?
2 When you add multiple USSD codes to favorites, at some point the horizontal scrollbar appears. It looks like it's because of the vertical scrollbar but the columns have fixed width. You can change the width but after closing the window, the values are restored. Would be possible to fix that, so the horizontal scrollbar disappeared?
