This is the Windows driver for the PCI modem that comes with the Great Quality PC sold by Fry's Electronics, GQ3131 (and possibly other GQ computers). In my case, the Windows driver on the manufacturer's supplied CD for the GQ3131 was for a modem used in a earlier GQ model. I obtained the driver from the CD supplied with the GQ6094 computer. Once installed, Device Manager shows the modem as an HSP56 MicroModem. The driver is made by PCtel.
