DSR is low while initializing the modem. Verify modem is turned on.

Could this be why it's not detecting a phone line connected to it? Modem has worked fine for months and all of a sudden, I get "Phone line is either disconnected or the phone is being used." when I was trying to send a fax from WinXP Pro, neither of which is the case. The title of the thread is what I see in the modem log.

See if you can dial out through Windows Hyperterminal. You may have gotten a surge through your modem. Also check modem properties in Device Manager.

Same thing with hyperterminal. The modem must be toast. Thanks for the help.

I removed that internal modem and am now using a Zoom 56k external dual mode. WinXP ID'd it and installed it as a Zoom 56K Data Fax Dual mode Modem PnP. I found Win2k drivers and tried to update it to something better and it installed as a Zoom External 56K LT Voice Faxmodem. Either one seems to work fine however when it dials it sounds like a rotary phone. I contacted Zoom tech support and this is what they had to say:

Quote:

There is no Windows XP driver for this modem. This modem should work with native drivers in the Windows XP operating system. Check the initialization string in your dialing program and make sure that it starts ATDT.

I'm using the fax feature within WinXP so where would I look for the initialization string for this program?
Thanks for the help

Initialization strings (or init strings) are special instructions for the modem. They don't change the modem, but they do give the modem extra commands to perform like "wait for dial tone" "turn off speaker" or "disable v90." If you enter an incorrect string for your modem chipset, it may stop functioning because init strings are fairly specific for each modem chipset.

To check for an initialization string:

Windows XP & 2000

Open the Control Panel and double click the Modems icon.
Highlight your modem and click the Properties button.
Click the Advanced button.
If there is an init string listed, write it down (in case you need it later)

Oh yeah, is this a usb or serial modem?

[TOAD6147]

Thanks for the response, PoonDoggy. It is a serial modem and there are no entries in the Advanced Settings/Extra Init. Settings box. I had always entered S11=50 in this feild to make it speed dial but that made no difference in this case. It still sounds like an old rotary phone.

Can you post a modem log? Maybe we can isolate the problem.

[TOAD6147]

It's a bit lenghty. How could we do that?
