I have been happily using WinFax Pro on my Windows XP Home PC without any problems. I can still send OK but every time I receive a fax the system locks up and I have to switch the PC off at the socket and reboot. (This Advent PC does not have a reset button for some reason).
I have tried uninstalling and reinstalling with no success. In desperation I uninstalled it again and activated the XP fax facility but exact same thing happens.
I have swithched off screensaver and tried altering the "wake on ring" settings in BIOS all without success. There has been no change to the modem or it's settings and I have no idea what caused the problem.
I don't use the Wake on Ring mode (I get incoming faxes as e-mails through Tiscali), but my mobo manual states, under Modem Use IRQ (Default: 3 in this instance), that if you want an incoming call on a modem to automatically resume the system from suspend mode, use this item to specify the IRQ that is used by the modem. The fax/modem must be connected to the mobo's Wake on Modem connector for the feature to work.
Under Resume by Ring/LAN, this allows the system to resume from a software powerdown whenever there is an incoming call to an installed fax/modem - again the fax/modem card must be connected to the Wake On Modem connector on the motherboard.
I thought formatting the hard drive would be a certain way to fix this problem but it hasn't. I can still send faxes but cannot receive them although at least now the system does not lock up when some one tries.
I can't understand why it worked OK for quite a while before this problem occurred.
(After the format I also installed Service Pack 2 without any problems.)
