Hi! I'd tested a lot of ZTE and Huawei modems and noticed that each of them can hang and become unusable anymore for establishing internet connection. Some modems may hang right after boot, some of them after connection was dropped several times. The problem is that the "Modem" port hangs and doesn't accept any commands. The only way to bring it to work is to reset the modem. This is very important issue for devices that needs to be connected through 3G modem all the time and work in automatic mode! So I created a patch that resolves this issue by checking modem port before establishing connection. If we get no answer during some time, we reset the modem and it can be usable again. Patch is attached to this message. -- Best regards, Yevhen
