PPP interface not responding to AT command

nidjo · Nov 16, 2012, 9:50 AM

I have 3G USB modem (iCON225). The modem interface is cuaU0.2. I've configured it and assign it to OPT1 interface and then enable it. In ppp log I have this:
Nov 16 09:29:31 ppp: [opt1_link0] chat: The modem is not responding to "AT" at ModemCmd: label.
Nov 16 09:29:31 ppp: [opt1_link0] MODEM: chat script failed
Nov 16 09:29:31 ppp: [opt1_link0] Link: DOWN event
Nov 16 09:29:31 ppp: [opt1_link0] LCP: Down event
When I use minicom the cuaU0.2 responds regularly to AT command, I've entered PIN, and dial ATD*99# and connection was established. But pfsense still can't communicate with modem interface.
If anyone has any idea, please, share it with me.

Thanks and by,
Nikola

I suspect the chat script is looking for a particular response, not "any" response.

HI!

Did you manage to resolve this? I have the exact same problem.

This modem needs the HSO driver as explained here: http://forum.pfsense.org/index.php/topic,45229.0.html
usho.ko needs to be loaded for the interface. I doesnt work as a regular modem.

Is there any way to get a working uhso.ko in pfsense?
