|sierra||/dev/ttyUSB3|
|Pantech |UMW190|/dev/ttyACM0|
|Pantech |UML290|/dev/cdc-wdm0|

===== Trouble Shooting =====

From command line install picocom

<shell>
opkg update
opkg install picocom 
</shell>

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>
