Can someone point me to a good modem how to? I am trying to setup a dial-in server and I cannot detect my modem but it is listed in lspci. When i run wvdialconf i get no modem detected. I have tried several different modems, lspci lists them but my configuration is obviously lacking somewhere, i have used the setserial command but apparently not correctly. i have read and followed several how to's but none by itself seems complete. Can anyone help by pointing me to a good source for modem config on Redhat and clones. I know not all modems are compatible so a suggestion for an internal modem that is know to work is also welcome. I have a lot of old internal modems lying around so one is bound to be compatible. I have tried conextant, agere, ESS, and smartlink internal modems. From what I understand I'd have better luck with an external modem but I don't have one lying around so.....
Thanks,

Let me make sure I understand what you are trying to do. If I am reading things right, you want people to be able to dial into your machine, and log in (or make a ppp connection). If this is the case, you need to configure mgetty for the ports you want. You then need to create entries for each line in /etc/inittab. They used to include examples in inittab, but they do not any more. There are examples in the inittab man page. There is also a fair amount of documentation included in the gmetty package.

Yes I want to be able to dial in and access the network. However I am having trouble dialing out from my f8 box as it does not detect the modem. The dial-in server is centos actually but it has the same problem, it cannot detect the modem that is installed. So I figure these as my first two hurdles, getting both boxes to recognize that they have modems then setting up the stuff you suggest with mgetty or do i have to configure mgetty to get my modem recognized in the first place? The mgetty config would only be needed on the machine i dial in to right?

Isn't this one of those s/w modems? I think you will need to buy the "conextant" drivers or use the NDIS wrapper with the windows driver.

I didn't think it was but you maybe right. I read that a great many conextant modems were compatible which is why I went with that modem. I will have to double check to make sure this one is hardware modem, can you tell by looking at the board?what would i look for? Would ndiswrapper give me all the functionality i need here? I have a somewhat large collection of internal modems at my disposal. Does anyone know of an internal modem that is compatible with linux? It doesn't have to be red hat based linux , though that is my preference. I appreciate the help.

I think that the easiest way to tell is to visually inspect the board. The ones that have a large amount of components, in my experience, are h/w modems.
Also, if you put the modem into your box and you can see a TTY appear in the boot dmesg(dmesg|grep -i tty), then linux has recognized and assigned it to a serial interface and you should be good to go.

Sorry, no modem was detected! Is it in use by another program? Did you configure it properly with setserial?
This is where i got stuck before. I am not using setserial properly. I can execute the command but i am assigning the wrong values i think but my syntax is ok or I would get an error from bash. One thing,at least, is clear, i do not understand the setserial command or what to set the values to.

The above is not proof that a modem is recognized. It is proof that two serial ports exist on the system. One port may actually be a modem, or it may not.

Does the user have permission to use serial ports? I think you have to be member of the uucp group to read/write to a serial port?

I have one serial port on the back of my computer. The usual assortment of audio jacks , Firewire, ps2 ports, and parallel port.
Is the fact that both serial ports show 'serial8250' significant? Is that the same device on both ports?

1. Check the BIOS of the machine and see if it allows configuration of a COM2 2. Remove the MODEM from the machine and see if ttyS1 goes away. 3. Profit.

I would expect a PCI card to have a different I/O port and irq. These are the values common to motherboard serial ports.

This looks more like a permission problem with the serial ports. One of the changes that was made is that the owner of the console no longer owns all the serial ports. You may have to run the scan as root. I don't normally recommend running as root though.

You may want to take a look at http://www.linmodems.org/ to see if any of your modem cards are supported.

Isn't this one of those s/w modems? I think you will need to buy the "conextant" drivers or use the NDIS wrapper with the windows driver.
I didn't think it was but you maybe right. I read that a great many conextant modems were compatible which is why I went with that modem. I will have to double check to make sure this one is hardware modem, can you tell by looking at the board?what would i look for? Would ndiswrapper give me all the functionality i need here? I have a somewhat large collection of internal modems at my disposal. Does anyone know of an internal modem that is compatible with linux? It doesn't have to be red hat based linux , though that is my preference. I appreciate the help.

Have we all forgotten The Linux Documentation Project, ha ha! ----> http://tldp.org/HOWTO/Hardware-HOWTO/modems.html
For what you are trying to do this is must-read stuff.
I might still have an old external 3Com serial modem that worked in Red Hat 6+...you might be able to find a similar one on Ebay at a good price. You can't expect most PCI modems to work. Dialup is pretty Stone Age though. It is hard for me to imagine someone would be willing to give up a phone line to a dialup connection any longer, when there are cheap DSL and cable choices available.

Let me make sure I understand what you are trying to do. If I am reading things right, you want people to be able to dial into your machine, and log in (or make a ppp connection). If this is the case, you need to configure mgetty for the ports you want. You then need to create entries for each line in /etc/inittab. They used to include examples in inittab, but they do not any more. There are examples in the inittab man page. There is also a fair amount of documentation included in the gmetty package.
Yes I want to be able to dial in and access the network. However I am having trouble dialing out from my f8 box as it does not detect the modem. The dial-in server is centos actually but it has the same problem, it cannot detect the modem that is installed. So I figure these as my first two hurdles, getting both boxes to recognize that they have modems then setting up the stuff you suggest with mgetty or do i have to configure mgetty to get my modem recognized in the first place? The mgetty config would only be needed on the machine i dial in to right?
Yes, you only need mgetty on the machine you are dialing into. But you are correct, you need to get the modem recognized as the first step. I am used to using external modems for this - that way, if the modem hangs in a strange mode, you can reset it without rebooting the machine. (I have had more then one modem fail to reset properly after a call.)

I suspect this is a "winmodem" which runs the connection using mostly software. You really don't want that...
If you want a modem to work for sure, look for a Telebit, Hayes, big old serial modems which do all the compression stuff in the modem. Connect serial, set the serial speed WAY up, 230400 bps comes to mind from memory, enable hardware flow control and compression, and you are ready to go. I can dig out other brands, I still have a ton of modems and "HUB-6" six port serial cards from the days when I had a modem pool and sold UUCP news and mail service on usenet.
The compression works well in ppp dialup, I used to run X to some machines, and it gave about 150kbit at the interface after compression. Then you learn about PAP, CHAP, and MSCHAP authentication. Good fun, chance to learn something pretty obsolete.
Get a real modem, which you program with the "Hayes command set," text config commands. That will at least get the modem recognized.
If I knew of a good voice modem which worked with Linux I'd put it to use, but the hardware is hard to find.

seeing it in lspci means, I think, that the PCI interface is visible. I don't think that necessarily means there's actually a real modem there though. It could be one of those "worthless winmodems", i.e, a device with a PCI interface and a phone jack but withouto all the hardware that makes it a real modem. If that's what it is, you may be able to find drivers for it for Linux, or maybe not. My experience with those things, limited though it may be, is that they're pretty crappy. I'd suggest springing for an external SERIAL (not USB) modem.
