Transfer files over serial communication ports from Windows (computer ports image by Alexey Stiop from

Serial communications are still widely supported and in many cases required by devices such as networking equipment, modems, point of sale systems and electronic appliances. When devices that use serial communications require system updates or configuration file changes, sending text or binary files over the serial communication line may be required. Use the Kermit protocol within a terminal console program to transfer files to a device over a serial communications connection from a Windows computer.

Skill level:

Things you need

  • Microsoft Windows 7 computer with a serial port and the HyperTerminal program installed
  • Serial console cable
  • Serial communication parameters for the device to which a file will be transferred
  • Serial device that supports the Kermit protocol
