This driver was uploaded from the "Acer Website". It is Identified as a "Rockwell" Model M1-5614PM3 56K modem. It was installed on the Acer 2800 Series Aspire Desktop Computers (in this case a 2856). I saved it to a temp file, then saved it to a floppy disk, unzipped it to a temp file on the computer I was repairing, selected the file to open and put it on a blank floppy as directed. To make final installation, I "updated driver" through the device manager "Specified Location" with a check mark in "Floppy Disk" and clicked "next". I had considerable difficulty finding this driver, so I am hopefully identifying it as I have will save you some of the misery I experienced.
