-use the DOS driver from Temporal Acuity Products (the driver was actually created by Voyetra). We have a copy of this in the disk cabinet and on our IBM computer. The name of the file that you need is "vapirsm.com". Just copy the file to your hard drive and type the filename (+ENTER) to activate the serial port.
