View 9 RepliesI'm new to ubuntu. I'm trying to get my US Robotics external serial modem working so I can use Ubuntu.
I copied
wvdial & dependencies:
libuniconf4.6
libwvstreams4.6-extras
libwvstreams4.6-base
to a flash drive.
How do I get them to /var/cache/apt/archives? I tried to copy and drag&drop wont work.

I have this USB modem P300U(SIM600 chip based) which works fine under wind@ws because it has it's own driver, but the clever seller told me that it worked under Linux as well. It was with Redhat 8 but I couldn't get redhat 8 to download. And until now absolutely false.
I have Debian with Kernel 2.6.32-5-686 I just want to send sms through this modem. It's not recognized as modem I'm frustrated because it's not useful for me if it doesn't work on Linux I looked for info but I can't make it work. What I get in my debian is:

On my CentOS 5.2 install I've installed a dual-port serial card based on the NetMOS 9835 chipset. I've followed the serial instructions, but everything they tell me to do is already done - see setserial outputs below. I've compared these values to the lspci output (below, NetMos card is at the bottom of the output) for the card and it appears right. Problem being, I can't use the serial ports. Oh and I did use search, and looked at every 9835-related article before posting this :)

Is it better to use a Usb to Serial Adapter Cable or a PCI Serial Port Card when attaching a serial port modem to a computer that doesn't provide onboard serial ports?I am leaning toward the USB to Serial Cable but do they work as well as a Serial Port Card? I have a US Robotics business class external serial modem that that I'd like to keep using for dialup internet connections.Here are the devices I am thinking of using:
USB To Serial Cable: KINAMAX CB-RS232 (Prolific Chipset)
PCI Adapter Card: SYBA SD-PCI 15024 --single port chipset=SB16C1052PC1
Background info
1) Compaq laptop, legacy free (no COM or LPT ports, USB only)
2) The laptop owner has dial-up and can't get broadband right now.
3) The laptop is running F12 with the PAE kernel.
4) Internal modem is a Conexant modem masquerading as Intel ICHxxx chipset. All attempts at getting a driver to work for this so far have failed.
5) I downloaded a Linuxant RPM but this failed to work.
So my only option that will get the computer back to its owner is an external modem using a Prolific PL2303 USB to SERIAL adaptor cable. When using the PL2303 cable my external modem appears as /dev/ttyUSB0 For the most part this works fine. I used the steps in the solution from the following thread
[URL]
The only problem I have is getting PPP to work THROUGH the cable. I have verified the cable is the issue. HOW?
1) I have tested all the modems on another machine with F12 through the onboard COM port. All modems dial, connect, then authenticate and maintain connection until I manually disconnect.
2) I have tested all modems used on the other machine with the PL2303 and can replicate the problem on that machine.
3) I have used more than one PL2303 cable and get the same behaviour.
Using the network configuration utility / wvdial / modem lights OR kppp produces the same results when controlling the modem located at /dev/ttyUSB0 So do I
1) have to make some configuration changes to relating to /dev/ttyUSB0
OR
2) is the something in ppp that needs configuring
OR
3) is it something else altogether that I am not aware of?
Right now I am using some software to emulate a null modem serial cable on my Windows computer connected to itself. For development purposes I need to have a null modem connection to a linux computer from a windows host. Is there any method of doing this virtually?
View 2 Replies View RelatedI have installed the KDE spin and am liking it so far. Except for the fact that I cannot get onto the internet. I rely on this ZTE USB wireless modem for internet and that just would not get recognized in Fedora. Plus, my Windows installation is down and I would love to keep it that way if at all possible.
I have followed a few instructions on this particular problem. I have modified the menu.lst file to account for the usbmodserial and product. The usb_modeswitch program has also been installed and the usb_modeswitch.conf file has been edited with the values I got from the 'lsusb' command's output.
But the curious thing is that when I actually execute the usb_modeswitch command, I get a message saying that there are no drivers for the ZTE device. Which means that I cannot go onto the wvdialconf part of it at all. Basically at this point I dont have a modem, according to Fedora. But it does get recognized as a ZTE device. That tells me that there is something right about what I have done so far and may only need to do a few tweaks here and there.

I have bought a so-called web'n'walk stick, which identifies itself as a "Globetrotter HSDPA Model". I managed to get it identified as a serial device (initially, it is detected as a USB drive), but I fail to get it working.

I own a Tata Photon plus usb modem which is a Hauwai EC 1260 and am not able to configure it on my ubuntu installation.
I have used it perfectly on my Mandriva/openSUSE installation so there should not be any question about its not supporting linux.
the menthod I used to connect to the internet was
lsusb :- to find the vendorID and productID.
modprobe usbserial vendor=0xAAAA product=0xBBBB with AAAA and BBBB being vendor and product ID respectively.
wvdialconf : to create the /etc/wvdial.conf file followed by subsequent editing of the file to insert username and password in it.
finally wvdial ... to dial the connection. The file /etc/resolv.conf was also edited the first time to include the nameserver values
but in case of ubuntu everything fails as soon as I fire wvdialconf command. It terminates with and error stating "modem not found".
In case of Mandriva/openSUSE wvdialconf used to check ports 7 to eight ports but in ubuntu it checks only 4 ports which perhaps arr labeled S0 to S3.
Please help me to sort this thing out.
One probable error might be due to the mounting of virtual CDROM inbuilt into the device which contains the installation files for its being configured on windows.
I am trying to get a Vodafone USB modem to work - Huawei K3765 (which is a rebranded E169). It's supposed to be recognized by the kernel and just added through Network Manager, but - no luck. I also installed vodafone-mobile connect from here: [URL] (as well as the other packages). What happens when I start it - it doesn't see the modem. It's seen as a CD drive, and clicking "eject", "unmount" or "remove safely" on it doesn't help - it disappears, then several seconds later appears as a CD drive again.

View 4 Replies View RelatedI have a Centos 5.4 server running kernel 2.6.18-164.11.1.el5PAE. It has an internal modem, and I need to be able to issue AT commands from a script to the modem. I need to simply dial a number and hang up. The relevant piece of my script is:
[Code]...
With an external modem, this works no problem. With an INTERNAL modem, the call never goes out. I fired up minicom to make sure the modem was working correctly, and if I issue those AT commands from within minicom, everything works great.
While minicom was running, I noticed a peculiar fact: WHILE minicom is running, the script works from the command line, and I can see all the AT commands and OK's in minicom, (minicom acts as a monitor). When I exit minicom, the script stops working. It appears minicom is creating a bridge between the com port and the modem itself. So, what is minicom doing that I'm unaware of?
The server's sole function is to run asterisk as a voicemail server (avaya wanted well into 6 figure territory to implement this....). This script is to dial an avaya FAC to turn the voicemail message lights on and off on the end users' phones.
My gentoo laptop doesn't have a serial port, so I got a usb-serial (RS-232) adapter from ebay. However when I plug it in, the only thing dmesg mentiones is: Code:usb 5-1: new full speed USB device using uhci_hcd and address 2I've tried to look for a kernel driver in "make menuconfig" by pressing "/" and typing 232. Nothing about RS-232. Device Drivers -> Character drivers -> Serial drivers has 8250 and UART as a module. Device Drivers -> USB support -> USB serial converter support has in-kernel: USB generic serial driver, and FTDI Single port driver as a module, but it still isn't getting recognized.Is there some module i forgot to enable, or do i have to download a separate module from somewhere?

Im a very basic Linux/ Centos user. I have Putty installed and a USB to serial adapter. All settings seem to be right as far as speed, etc, but I'm not sure how to list the device to open for the program. The default location it gives is "/dev/ttyS0" Trying to find where the USB is located using the "/sbin/lsusb" command gives me-
Bus 001 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 004 Device 002: ID 0557:2008 ATEN International Co., Ltd UC-232A Serial Port [pl2303]
Bus 004 Device 001: ID 0000:0000
So I think this means that it is on bus 4 correct? So how do I list this for putty to open the device.

I can echo output into the device from windows and see it, but
