Compaq Presario, with Windows ME.
This is the 5000 model with the TI ADSL card.
The "Windows Driver Model" (WDM) installed in a Compaq Presario with Windows ME assigns the modem to com port 3. From what I understand, this is a product of the UART chip on the Presario motherboard.
The modem is a 56K with a PCTel chip.
The modem, as well as the com port, show in the device manager, and detect no conflicts.
Attempt to dial up and receive the error message about no dial tone.
Phone line checks out fine.
Is there a way to reassign the modem's com port to com 3, to match the WDM assigned port?
Note: Windows Millenium Edition
Can the UART be disabled via BIOS?
Is there another way out of this predicament?

Hi

1. Voice mail on the phone line
2. The phone line is not connected properly
3. Modem setting such as call Waiting which Knocks You Off
4. Hardware problems with the modem

see this article and check the links in that page for other problems.
Connection Error: No Dial Tone

Right Click My Computer-> properties -(TAB TO) device manager-> (click) the "+" near the modem-> slect the modem - > click -> properties-> (TAB) to Modem - in port choose the port you want from availble ones. exit then reboot when asked.

My apologies.
I thought that I had made it clear that the phone line checked out fine and that I was working within Windows ME. I suppose that I didn't.
I not only checked out the phone line, I put the modem into another machine to ensure that itwas operable.
In Windows ME, you are not given the choices, in the device manager, to change the com port for the modem.
Sorry, I will try to make myself more clear in future questions.
Thanks anyway

This 'usually' works for me with most modem problems like yours.

Download and extract the latest version of the modem drivers onto the PC.
Use a folder such as Drivers\modem

Go to Control Panel, Modems.
Remove ALL related modems.
Close control panel, and re-boot.
When Windows finds the modem, direct it to use the files that you extracted for the driver install.

Did that, Sir.
Compaq's UART and WDM seem to allocate the com ports seperately each time I do.
The modem is going to com 1, where the Windows ME is looking in com 3.
It sounds like something an end-user might say, but,"It used to work".
The client would like to keep the ME, or there would be no problem. The rest of the network has win 2K.
Thanks for trying.

if you are using aol 7.0 or arround there, aol is common with not being compatible with some\most modems. it has to do with the chipsets and how aol uses its own drivers- for instance my local big computer store only carries one brand (type) of new modems that works with aol i had the same problem on the same model compaq

It had AOL, but it's gone now. The only connection it has is my IT connection, created manually.
It has to do with the combination of: Compaq & the UART chip , WDM, and Windows ME.
If I could just reallocate the com port via the modem to match comport 3, like UART and WDM are insisting on.
Taking AOL into consideration was a idea.
Thanks

One setting that is useful for these soft modem problems is to go to Control Panel>System>Device Manager>System Devices>PCI Bus and change enumeration from Hardware to Get From Bios before installing the modem. The proper driver is essential. Fortunately, broadband users have been spared the tediousness of modem AT commands and other "black arts".

I really thought that you were on to something with this attempt.
Unfortunately, even this didn't cure this situation.
It seems that, since the NIC allows a network broadband connection, that a dial-up modem is out of the question.
It is either broadband or operating system change.
Thanks for trying.
