I've just tried to send a fax from my desktop.
I have a US Robotics Dial-Up modem (new) and using MS Fax/Scan system.
I have used it a dozen times over the past 6 months.
Today though, nothing happens.
I press ctrl+P to the printer list. I select Fax, which opens the Fax/Scan routine. I input the fax number & click Send.
The Fax/scan page drops away - as usual. This is where the 'fax status' page pops up whilst it dials the number,,,, but today nothing happens.
I've checked the cable and all is well.
The only thing thats happened recently, is that I had to run a System Image Restore last week, & I havn't sent a fax since.
I looked at Fax in the C.p > Printers, and it says connected & ready. There isn't a problem in Device manager.
I'm sure that many many years ago, there was a way to test the modem in situ.
