Error 630 PC not rec resp from modem.

Have you checked for conflicts in device manager?
If there are any yellow "?" or "!" correct these before proceeding.

First, go to control panel / modems.
If you see modems other than the modem that is currently installed, select them one at a time, and remove them.
You may need to reboot before proceeding to the next step.

Click on the diagnostics tab.
Select your modem,
Click on more information.

If you get errors here, you have a driver problem.
Likely remnants of an old driver.Check with the mfg of any old modems for driver removal instructions.
I have had to perform search and seek through both the Windows folders, and the registry.
WARNING! Before editing the registry, be sure to back it up.

The next thing to try,is to remove the modem, from the general tab, shut down, and move the modem to another slot.

Check for updated drivers for the modem. This has curred a number of modem problems for me.

If the modem passes the diagnostics, you may have a phoneline problem. Some modems are sensative to phone line polarity. You can get a phone line checker at Radio Shack for under $10 to check for this.

Also, many a modem problem has been traced to a bad phone cord elsewhere in the system. Try disconnecting all phones from the line. If possible, plug in only the modem at the point where the phone line enters the house, with the rest of the house disconnected.

This error will appear when you attempt to use Dial-Up Nnetworking
Open the Control,double-click Add/Remove Programs,select the Windows Setup tab,click on communcations or accessories and click details,remove the check mark from dialup networking and then click OK
Reboot computer and return to windows setup and enable Dial-Up Networking and reboot computer.

If the modem is using a new serial port assignment due to new devices that are installed by Windows,

When this occurs,change the properties of Dial-Up Networking

Programs in the Startup Folder can also cause this problem

Click->Start,select Programs->Accessories->System Tools then System Information,On the Tools Menu,click System Configuration Utility
Click the Startup tab.For Programs that may control your modem,click to clear the check box for the [program.If you are unsure which program to disable,click to clear all of the boxes except the following

Here are some possible causes and resolutions:

----------

This error message can occur if the modem is using a new serial port assignment due to new devices installed by Windows 98 hardware detection.

Check that the modem is plugged in, andif necessary, turn the modem off, and then turn it back on. Change the properties of the Dial-Up Networking connection to use the new modem settings. Programs in the StartUp folder can also cause this error message. Disable those programs one at a time to test this.

----------

This error may indicate the modem is damaged, not connected, or installed improperly. If you have an external modem, make sure the cable is connected, and the modem is powered on. If there have been electrical disturbances (including thunderstorms or power failure/surges) since the last time the modem worked, that may be the cause. If the modem has never worked, double-check installation, and if possible, try the modem in another system.

----------

This error may also occur if your modem is being given a bad init string - with a command that it does not support. Remove any extra settings/init string. Make sure the modem is installed with and using the correct .inf file - examine modemlog to see if there is any modem response.

----------

Windows 95/98/NT - This error may occur if you have special telephone company provided features - like distinctive dial tone - including dial tone stuttering signaling voice-mail services, etc. Several methods can be used to fix this including the use of commas in the dialed number, or changing the wait for dial-tone time.

go to your bios in peripheral devices settings and examine your ports make sure they are not disabled, or set to auto instead set it the first port to 3f8h and the 2nd port to 2f8h this is your com1 and com2. save and exit bios.when windows is restarting press f8 to go to start menu and select safe mode. uninstall your modems thru the add remove programs or in your device manager or in your modems applet in your control panel. restart your pc and let it boot normally windows will ask you this time that it found a pci communications device put it in your modem cd driver to your cd driver and point to there when windows will look for its correct driver this will normally install your modem. before using check its diagnostics in the modem applet in control panel if your modem responds the commands it supported will popup immediately.

Did you replace the wire from the computer to the phone jack?
Did you check in device manger to make sure the modem is enabled?

At the dos C\: the at commands echo back, but there is no dial tone the original modem was working them stopped. Tried to upgade to a 56k INT got the same message. Then tried a 56k EXT got the same message.
