If you do not have integrated serial ports on your platform, you If your platform has integrated serial ports, you only need toĬonnect them using a null modem serial cable. Minimum, you will need two serial ports with a null modem serial, Your setup requirements will depend on your hardware platform. Techniques can be used to communicate with serial devices thatĬommunicate using binary protocols. In this example, we are using ASCII for clarity, but these same AfterĬompleting this section, you should be able to communicate with anyĪSCII-based serial device attached to a Kura-enabled embedded gateway.
