Internal modem not detecting dial tone

I have an iMac G3 CRT 333MHz (Lime) which is having trouble connecting to my dial-up internet connection. I am fearing that my internal modem is 'burnt out', and am wondering if anyone out there has any additional troubleshooting tips, or any advice on purchasing a new external modem.
The trouble started after a lightning storm, which also disrupted internet connections for my roommate's PC (I don't know exactly how he fixed his, but he is connected via a DSL modem and says he simply restored some modem drivers). I have noticed, however, that he removed his 56k modem...
When I attempt to dial-up from my Mac, I get a message stating "Modem did not detect a dial-tone or the line is currently in use..." I have checked and double checked that the phone line does indeed have a dial tone, and tried connecting through through various outlets throughout the house. I've disconnected all other phone hardware (except the DSL filters) and reached the same result.
I am currently running OSX (10.3.9), and also attempted to dial out after restarting in 9.2.2. (Same result). After that, I dug out my install CD and reinstalled 10.3 (same result)
From each OS, I've run system profiler and recieved no unusual information about the internal modem. The computer definitely senses that I HAVE a modem (Apple Vsn 0007-1,9/2/1998 v.90) That modem simply can't seem to detect the dial tone.
I have also confirmed my modem settings, tried checking and unchecking the 'sound' and 'wait for dial tone' boxes. My internet provider is NetZero, so I have attempted to dial in using their software, as well as directly through Internet Connect. All attempts return the same message. (and the NetZero account is still active, I have accessed it from two separate computers).
Any thoughts out there if there are any further settings or or software/OS variations I should try? Or are my suspicions valid that the storm somehow fried the modem (there were no power interruptions during the storm... only modem troubles)
My next step might be to find an external modem. I've not seen any Mac-compatible 56k modems in stores. There is a Apple USB Modem in the Apple store, but it requires OS 10.4.3 and a computer 'without a built-in modem', so I don't think that will help me. I've also considered using Airport to share my roommate's DSL connection, but I believe that my model of iMac is not airport compatible...
I also have a dead iMac in the closet (DV model) with a blown ethernet port, broken fan, and damaged hard drive. I'm not above cannibalizing either machine to get the other working until I can afford a new G5...
Any thoughts, suggestions, or shared experiences would be greatly appreciated!!

The only thing I can think of is to go in to the modem settings and choose ignore dial-tone. That way even if it's not getting a good tone the iMac will continue to try to connect. This is also important if you have a voice mail system that varies the dialling tone whne you have a message as I know that stops my father's Win98 box connecting to the Internet unless the equivalent option is checked.
You can update your email address to a current one here. If the Apple ID (i.e. the one you login with) is old don't worry that's pretty irrelevant.

Internal Modem Not Getting Dial Tone - Failed or Settings? Solution?

I have just refurbished my old G4 FP iMac for my grown son to use. He has only dial-up service. There is a dial tone on the phone line (verified via telephone handset). After an attempt to connect, I get a "no dial tone" message. I hear no audio of the dial tone or connection sequence, even with volume fully open. Believing the internal modem had failed, I purchased an in-line Apple external USB modem. I obviously did not read the fine print carefully enough, because in troubleshooting I ran across a note saying that I need 10.4 or later to use the external modem. I have 10.3.9 installed, and 10.4 costs about $150 these days. That's a lot of $$ to solve what might be a simple modem or system settings problem. Or maybe I don't really need 10.4?
Also wondering (if it is a failed internal modem) whether I can purchase and replace the inernal modem itself.
Any suggestions?

Internal modem/fax: no dial tone

Hi folks,
Yes, another 'no dial tone' problem
I have a 20" iMac G5 running 10.4.8 in the U.K. that seems unable to make a connection via it's internal modem to the internet or dial out to send a fax. Whenever it tries to make a connection it will eventually timeout after ~10 seconds claiming there is no dial tone - there is a dial tone on the line however. I've had a look through other posts mentioning things like this but there doesn't really seem to be any solutions out there that I can see. After just going out to Kinkos to send a fax for the princely sum of £8 (~$16) I'd like to finally get this flippin' thing working!
The following things have been tried:
- The modem has been connected to a regular phone line (connected telephones have a normal steady dial tone, no answerphone tone you can get with BTs 1571 service in the UK)
- The modem has been connected to an active DSL phone line via the filtered phone socket
- Different phone cables have been tried
- A different user account behave exactly the same
If it makes any difference, this iMac was originally bought in Switzerland. The international preferences have been corrected to make the iMac think it is London. I've never been able to get the modem to work, so I'm not sure if the modem is at fault, or if it's an OS X problem...
If anyone has any ideas/suggestions, I'm willing to try anything.
Cheers.

"Q: Why my modem is not getting Dial Tone?
6. Many voicemail systems use a "stutter" dial tone or beeping when you pick up the phone to indicate that you have voicemail waiting. These unexpected sounds can make the modem think there is no dial tone.
7. In extreme case, your modem may not be designed for the phone system in the country in which you are trying to use it."
Acoustic couplers should work when all else has failed...
http://www.roadnews.com/html/Articles/a31.htm
You can also run into problems with dial tones overseas. Your computer may not recognize the dial tone of the country you are in as a "dial tone." Depending on the modem software you are using, you might need to put a check in the Ignore Dialtone checkbox in your modem software setup window.
What about digital telephone systems?
Modems communicate using analog or sound signals while many new telephone systems use digital signal processing. Digital systems are unable to process analog signals, making it impossible for modems to communicate.
Seems that there very well might be some diff in the Modems between Switzerland and UK...

Faxing - Modem Does Not Detect Dial Tone

Hello Everyone,
I suddenly have a need to send and receive a Fax. I have a phone line plugged into the modem port on my G4 and on trying to send a text fax, not much happens. Error message to the effect that the modem is not detecting a dial tone. Same cable that works fine on the phone itself.
Can someone either help with an answer or direct me to a page with more detailed instructions than the "Help" file is providing?
John

I have the same problem. I thought I would begin to use my several years old Powerbook to send a simple fax. As it is I have to use my old G3 to fax. Even with Faxstf pro on I still can't get it to work. Fax STF says that the modem is only set to receive and I just cannot change it in the settings. I've trashed the preferences and the program. I am at a loss after having spent a day trying to figure this out. I am on a dedicated phone line that works just fine. I would really like to just simply fax from my powerbook G4. The modem is as follows:
Modem Model: LastDash
Interface Type: USB
Modulation: V.92
SKU Name: UCJ
Hardware Version: 4.0
Firmware Version: APPLE VERSION 2.6.6
Driver: InternalUSBModem.kext (v2.6.6)
Country: B5 (United States, Latin America)

New internal modem not detected

I installed a US Robotics v.92 faxmodem (model 5660A) into a dual 1.8 G5, 10.4.3. This computer came without an internal modem, but I need to send faxes occasionally.
The modem installed into a PCI slot. In the "About This Mac" apple menu selection, no PCI or modem info appears. I have tried resetting the PRAM, searching the US Robotics and Apple web sites for drivers (nothing for Macs.)
The modem was sold as a Windows and Mac compatible modem. Any suggestions?

Hi Shau,
Welcome to the forum.
USB DSL modems are notoriously buggy when it comes to OSX. Continuous need for updating drivers which, more often than not, cause more problems than they solve. My advice would be to invest in an ethernet adsl router. They do not require drivers, you just plug them in and with a minimum setup (literally seconds) you're up and running. Your ISP may be able to exchange the USB modem with an ethernet adsl router for you at no additional cost. Failing that you can buy one for literally tens of pounds.
More info on routers can be found here:

Dial-up Modem not detected

Problem:
My system isn't recognizing/finding my internal modem.
What I have:
wvdial and gnome-ppp set up. From the Wiki, I gave all users permission to use wvdial.
What I know:
I ran PuppyOS and was able to get the modem to work - so it's there and functions. (PuppyOS uses wvdial) The modem is at /dev/ttys_PCTELO and I have an init string (though it's a bit different than the one gnome-ppp shows.)
Question:
How do I get Arch to find the modem?

Maybe you could take a look at:
http://wiki.archlinux.org/index.php/Dia … aler_HOWTO
It (supposedly) enables you to connect without a dialer.

Internal Modem No Longer Dials

For the first time in a while I tried to fax something off my Mac today and no matter what I did, the mode wouldn't dial the number. I am using the Fax PDF command. I tried entering the phone number manually, and I tried creating an Address Book entry with the number, but neither one worked. It launches the Internal Modem icon in the dock, and when I went to the Internal Modem window it would show the fax preparing to send, but never dial and just go into a hold for a few minutes, then try again with the same result.
Next I went to Faxing under Print and Fax in the System Preferences and selected Receive Faxes on This Computer to see if maybe that would make the modem dial when I tried to fax something, but that didn't help.
Finally I tried going into Network under the System Preferences and selecting Modem. There I clicked off the Wait for Dial Tone Before Dialing to see if that would get it to dial, but now it just says, "Waiting for Modem to become available." I've faxed off this computer before, so it should work. Does anyone have any idea what the problem is or how to fix it? (Under About This Mac, the Modem information lists the modem driver as com.apple.driver.AppleSCCSerial (v1.3.0), and I'm afraid that something has happened like the driver got updated in one of the automatic software updates to a version that for some reason won't run on my Mac, even though I'm using 10.4.11.) If anyone can help, I'd sure appreciate it!

Hi AdmrlLocke!
j.v. is doing an excellent job of assisting you, but see if the info posted below, is helpful.
You cannot be connected to the Internet, while you are sending, or receiving a FAX.
Not all DSL Cable Modems can be configured to send a FAX using the OS X FAX function.
Review this KB Article Can I fax with my cable, ADSL, DSL, or ISDN modem using Mac OS X 10.3?.
I have DSL as well, and when I want to send or receive a FAX, I disconnect the Ethernet cable from the Mac Ethernet port, plug a wire from the wall jack to the Internal Modem port on the Mac.
I have a two port Splitter/Filter plugged into the wall jack.
The Cable/DSL Modem wire, is always plugged into one of the ports on that splitter.
When I want to use the FAX function, I plug the telephone wire into the other port, but I do not unplug the Cable /DSL Modem.
The Splitter/Filter may not be a necessity. If you don't have one, just unplug the Cable Modem wire from the wall jack, and plug in the telephone wire.
I then set the Network System Preferences, back to the Internel Modem, deselect the Built-in Ethernet, selecting Internal Modem, and dragging it to the top of the window.
This of course will disconnect the Mac from the DSL connection, and you can then use the Internal Modem to send or receive a FAX.
Also review this Topic Faxing, for additional tips.
Additionally, when you enter the recipient FAX number, use this format 1-area code-xxx-xxxx.

Apple USB modem stopped recognising dial tone

Running Snow Leopard (10.6.8) on a 2007 iMac. Have been using an Apple USB modem for the last several years, and as recently as last week successfully sent out a fax, but suddenly today it does not detect the dial tone (although I can hear it), and hangs up after just 2 seconds. It detects and receives incoming faxes. Is there any way to dig into the preferences to set a longer wait? The system preferences panel for print/fax shows no option for 'wait for dialtone'. Or do I need to reinstall the driver? And if so, where can I download the driver?

I have exactly the same problem with my Apple external USB modem right down to it showing up in the Profiler. It complains if I unplug it while it's supposedly faxing something. It worked until April 30th, but it hasn't worked since then. However, I don't recall installing any new drivers that would have caused this problem. Even stranger, the modem still works with my old PowerBook G4 which is also running OS X 10.5.7.

Apple Internal Modem not working since installing OS X 10.5.2

Folks,
A friend of mine just installed 10.5.2 on his G4 Tower which has an Apple Internal 56k modem.
The modem was working properly under 10.4.11.
Now that he is using 10.5.2 the modem will not dial.
Network (in System Prefs) sees that there is a modem, since it allows him to create an Internal Modem connection, but it will not dial the modem.
Has anyone else seen this issue? Any solutions out there?
Thanks!
Tony

Tony,
The +Intel iMacs+ don't have internal modems so you probably won't get much help around these parts. Try posting over in the PowerMac G4 forums:

Network Status Internal Modem not set up to Fax on PB G4 High Res

What do I need to do to set up the Internal Modem to Fax. I connect to the internet only using Airport & cable ethernet. In System Preferences > Network > Show > Network Status Airport is on top of list. Internal Modem is the only other item shown; It says Internal Modem is not set-up. I do understand that it is impossible to send a fax via Airport. But what does setting up the modem mean since I do not have or use a Dial-up internet connection. Configure button takes me to PPP, TCP/IP, Proxies, and Modem. Under the modem button I have chosen Apple Internal 56k Modem v.92 this is the only option I can choose. What can I do. I have both the Fax status and Modem status in the menu bar both stay at idle while tring to send a fax. Can anyone help?
Thanks Axlan

Modem Not Detected! UPDATE

Ok I posted this a while ago but I selected my internal modem for AOL V.5.0 (OS 8.6) and it wasn't detected(Trust me I tried everything). Well I was reading my Internal Modem read me amd it sasid that in the modem control panel it should say "Connect via Internal Modem" and mine says "Connect via <no serial ports available>". Ok. I think something fishys going on. I can't select from a list near the Connect via thing. My system profiler says it detects my modem. Can someone help? Please?
In loving memory of TP2GO

I read back through as many of your past posts on this subject as I could find, and there's one subject missing that used to get a lot of posts here. AOL tended to corrupt the Modem Preferences, or replace them ... 'can't remember which.
The clean system install that Ron suggested is probably best, but you can go to the Preferences Folder in your System Folder and throw out the file labled "Modem Preferences", and anything to do with AOL Dialer. Restart the computer and see if there are some selections in your Modem Control Panel.
Instructions for a clean install are on the OS CD in a read-me file.

Help! Modem Not Detected!

need help. I just got my iMac today and I installed the AOL 5.0 thing. The AOL program isn't detecting the intenal modem. It is V.90 I supose, I do not see the modem cotrol panel in the apple menu. I tried all the apple internal modems form the list, I pluged in the phone line and I is saying Does Not Detect. I am not on my iMac so I can't take any confusing comands right now. Thanks. PLEASE HELP!

Tiger -
Let's try one more thing. Open Macintosh HD. Scroll down to System Folder. Open System Folder and scroll down to Control Panels. Open Control Panels and see if Modem Control Panel is in the lineup. It's probably not since it doesn't show under the 'Apple'.
Just under Control Panels should be Control Panels (Disabled). Open that and see if Modem is in there. If it is, drag it to the closed Control Panels folder and do a restart.
If it's not in the disabled panels folder, do a Sherlock search for Modem and see what comes up. I guess it's possible that the modem panel has been put somewhere else in the HD. If it shows up, drag it to the closed Control Panels folder as above.
If the modem panel is totally absent from the HD, about all I can think of is to perform a Restore using the original CDs that came with the machine. But before that, I'll pose the problem to the larger gang here.

Apple Internal Modem not accesible maybe not present?

Previously functioning internal modem used for faxing not visible as a choice in the print center. Under the Apple Menu, About This Mac, Modems shows "no information found"? Fax-STF shows "communicating" ? What is my problem. Is the internal modem gone or somehow not activated.
Frustrated in NV,
Bill

OK, I looked on the Apple website at the specs for the MacBook Pro, and they do not come with an internal modem, nor is it an option. So I have no idea how you faxed before, but you must be mistaken. Perhaps you did an eFax? To fax, you must use a modem connected to a phone line. Your post is very confusing, to say the least. There is no internal modem for either of these models. I have the external USB modem, which is also what is recommended for the MacBook Pro.
