Connect to your 3g dongle
<shell> picocom -b 115200 /dev/ttyUSB0 </shell>
Change to your 3g port (USBx). If you get he wrong port you will get this error at he end when you type anything.
<shell> Terminal ready
FATAL: write to term failed: Resource temporarily unavailable root@Gargoyle:~$ </shell>
or when nothing is plugged in (3g dongle) <shell> FATAL: cannot open /dev/ttyUSB2: No such file or directory
</shell>
success will look something like this
<shell> +ZDONR: “Telecom NZ”,530,5,“CS_ONLY”,“ROAM_OFF”
+ZPASR: “HSUPA”
+ZDONR: “Telecom NZ”,530,5,“CS_PS”,“ROAM_OFF”
+ZPASR: “UMTS” </shell>
ZTE modems
ZTE USB modems by default support self-installation and auto-run functionality. This is a problem with linux devices and needs to be disabled.
To disable run
<shell> picocom -b 115200 /dev/ttyUSB2 AT+ZOPRT=5 AT+ZCDRUN=8 </shell>
