I read it and thought I was asking properly. I can't ask like a tech
because I'm not a tech. It seems no one here has ever had a problem
with their dial-up connection or got the "Windows can't detect a modem"
error.
They have a suggestion here, to try the "Query Modem" button. In
Device Manager, you'd find the hardware entry for the modem,
and then use the query button. If the serial port isn't "busy"
already, you should see the light flash (it if was an external
modem). That is a way of proving serial communications are working.

Other than following their advice there, you'd need to take note
of any error numbers, when it doesn't work. You might see
a three digit number for an error number, for example. Based
on that number, if might be possible to guess at the problem.
The information entered in the Dial Up Networking dialog box,
has to continue to be correct for what you're trying to do.
If some detail changed (say, different COM port), then you'd need
to fix that.

And I do use a dialup modem, but as a backup system. If my
primary provider (ADSL) stops working, I use the dialup modem
to connect to a free ISP, and then web surf to the ADSL
provider to check their hardware status web page, to
see if they think everything is working properly. It gives
me some idea, whether I should be in a hurry to phone them
or not. If they know about the problem, it saves a phone call
and waiting on hold until a tech answers.
I've had problems with the modem. The usual problem is the "serial
port is already in use". That one is a killer to fix. On my
current computer, I have a USB to RS232 adapter, then an external
RS232 dialup modem. And fortunately, the USB to RS232 has a tick box
in its custom control panel, that has fixed my port already
in use problem.
I suggest recording the *exact* wording of the error message
and posting that. Or, if a three digit error number is reports
by dialup networking, you could post that information. For example,
this site has information on various error codes.
