Verizon UM150 3G Cellular Modem Working on Linpus

NB: This should work with other EV-DO modems and other carriers, although you will have to figure out what your device is named. Possibilities include /dev/ttyUSB0 as well as /dev/ttyACM0.

OK, I finally got it working! I have the same modem working on my laptop running Ubuntu, so that provided me with some insight. Here is the full story:

On Ubuntu the modem appears as /dev/ttyACM0, but on Linpus it was not recognized at all. This week I finally installed "A patch for Huawei CM (Multi language)(180068)" in the hope that this would let me use my VZW modem. Unfortunately I was not able to get the resulting Mobile Partner program to work with my Pantech UM150. However, after installing this "patch" I noticed that the modem was being recognized by Linpus as /dev/ttyACM0, same as on Ubuntu.

On Ubuntu I simply use the ppp dialer to dial the modem and I have set up menu items to issue pon and poff commands to connect and disconnect. Since wvdial (pronounced "weave dial") is available on Linpus, I figured I should be able to use that.

I modified /etc/wvdial.conf as follows, similar to the ppp configuration I use on Ubuntu. I simply started out with the default wvdial.conf and modified it to meet my needs, commenting out (#) any lines that didn't seem necessary or that appeared to give errors:

[Dialer Defaults]
Phone = #777
APN = internet
Username = firstnamelastname
Password = xxxxxxxxxx
Stupid Mode = 1
Dial Command = ATDT
Modem = /dev/ttyACM0
Baud = 115200
# Init2 = ATZ
# Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
# ISDN = 0
Modem Type = Analog Modem
# Init1 = AT+CPIN=0000

A few notes based on information I found on one of the Ubuntu Community forums:

(1) The number to "dial" for Verizon Wireless is #777. (2) The user name should be the name assigned to the Verizon Wireless account, run together and all lower case, viz: johnsmith if your name is John Smith. (3) The password should be the ten-digit telephone number assigned to your modem.

Once I had this set up I plugged in the modem, opened a terminal window, and issued the command wvdial. This resulted in an error message to the effect that /dev/ttyACM0 was busy or unavailable. This frustrated me so I put the project aside for a short time and went off to do other things. Suddenly inspiration struck! I started up the Aspire One, plugged in the modem, opened a terminal window, and typed sudo wvdial. Bang! I got a connect message followed by a report on local and remote IP addresses and DNS IP addresses. I was on line!

To finish up the project I added an item to the right-click menu to issue the sudo wvdial command in a terminal window. (Simply issue a <control><c> while in the terminal to close the connection and hang up the modem.)

Perhaps others will be able to supply some refinements, but so far this is working OK for me.
