Pcmcia Umts


Hi !

I have a Novatel Merlin U740 PCMCIA wireless network modem.

I need to have it running on my laptop (slackware 10.2) but I can't find any drivers or information on google.

When I plug the card into the computer, dmesg tells me that some usb stuff have been inserted but wasn't claimed by any driver or module.


Any idea or help to make this working?

PS:I need to have it running within two days so it's quite urgent

Thanks.

You could try ndiswrapper if you have a windows driver for the device (.inf file in the installation cd), but the card does not seem to be listed on the wiki, so not a very optimistic suggestion.

Merlin U740 PCMCIA

Have you had any luck with the Novatel Merlin U740 PCMCIA wireless network modem?

Can anyone else help??

Yes I managed to use it as a standard 56k modem. That was pretty slow but did the work for mail check etc...

you have to load the usbserial mode like this:

Code:
modprobe usbserial product=0x1400 vendor=0x1410
then you plug the card into your laptop


A red light should blink (IIRC).

then run the minicom tool with:

Code:
minicom -a
(this step require that /dev/modem is linked to the good device (generally ttyUSB0 but check with the output of dmesg)

When you're in, do the following:

Code:
at
at+cpin=xxx //here replace with your own PIN code
//wait a moment here and you should see the a green light instead of the red one
at+csq   //this is to check the signal strengh
//from now this is specific to Orange (french carrier)
//I think some search on google can give you the informations 
//you need for this part of the configuration
//in fact most of the pages I read were about vodafone configuration...
at+cdgcont=1,"IP","orange.fr","0.0.0.0",0,0
//then we dial the number (don't know if this is also Orange specific but I guess it's not)
atdt*99#
After this the light should blink approximatly twice a second and be green.

Then we can juste use pppd to establish the connection

Code:
pppd ttyUSB0 defaultroute usepeerdns
Then the light stops blinking and you're connected, you can check your IP adress using ifconfig and should have some ppp0 network interface up.

You may have some problems with name resolution (DNS), if so, check your /etc/resolv.conf file, it should be a link to some /etc/pppd/resolv.conf file (the one pppd use and file from the DHCP server).

Hope this help...

U740 using AT commands and PPP connection at the same time

Hello,

I using Novatel Merlin-U740 on Mandriva 2006. When insert the card it creates ttyUSB0 and ttyUSB1. I am only able to use ttyUSB0 and launch my ppp scripts to connect to my HSDPA network. Once connected I am not able to use ttyUBS0 to launch minicom or other software to execute AT commands as it says ttyUSB0 file is locked by my ppp . Mainly I am interesting in finding signal strength and Bit Error Rate (AT+CSQ). I see that ttyUSB1 doesnt serve any purpose. Has anyone tried using AT commands or get signal strength info once ppp connection is already launched?

I havent found any support from Novatel Merlin website.

Thanks in advance
