I've installed sereval modems in a Win 98SE machine and they will connect once and then after I get no dial tone error messages, checking the modem in control panel diagnostics it gives me ports already open. If I delete the modem and reinstall andgo to diagnostics it shows OK but when I go to connect I get no dial tone, if I go back and check it again it shows the ports already open, any ideas?

Many modem drivers have a defect that once they open a port thy will not close it until the machine is rebooted. Your best option is to check with your modem manufacturer and see if they have any updated drivers. There is no known workaround to this problem other than rebooting your machine or getting a different type of modem.

Just a note to add to whats already said.

When you reboot make sure its a cold boot as the internal modem will need all electricity purged to make it a TRUE reset. Sometimes a simple warm boot does work but not always. Also like stated. check fornew drivers and also check for a currupt registry/virus.
Use System mechanic iolo.com to clean up your registry.
Then check for viruses.
There are many viruses that do mess with the registry and make the system act strange at times.

Good Luck!

Does the modem have the ports set at Com5-Com8?? And/Or does it have a Rockwell/Conexant chipset??

If so....remove all the appropriate .inf files from c:\windows\inf\Other and then run Regedit. Remove all traces of Rockwell/Conexant. Reboot and then reload the drivers. Check you have the right drivers and are not using R56PCI drivers if you should be using HCF, HSP or HSF. If the modem does NOT have 3.5mm jacks for speakers and mic, use a NON-Speakerphone version of the driver.

Try adding the Init string of ATZ. You put in under properties & advanced then find category callrd 'extra settings' This is just a generic string to tell the modem to reset.

But, if you have tried more than 2 modems - then it could be that DUN (dial up networking is corrupted. When you get the port open error message, hold down ctrl & 'Alt' buttons then tap the delete key. You should see a window pop up that says close prorgam dialog box. You should see a list of programs running. Look for a file named 'rnaapp'. End task on it & see if you can it

First thing I wouuld recommend is booting to safe mode. The open port error can be caussed by multiple "ghost image" modems this can not be seen in normal windows but can be seen only in safe mode. removing all modems in safemode and rebooting then installing the proper driver will normally fix this.

I will also ,look for the .ini file right now I find my notes, but there is a .ini file that will hold the modem in an open status will research it and get back to you
