TM4C1294NCPDT: Cannot establish communication through virtual COM port enet_io

Hi,

I am starting with the TM4C129. I did play with the gpio, timers. Now I am trying to run the enet_io example for ethernet communication, however, I cannot access serial communication and read the assigned IP address through PuTTy for example. I can connect to the COM port but no data are displayed. I did reinstall twice the stellaris drivers and in the device manager it is visible with the updated drivers. 

Any clue?

    Hello Lukasz,

    What settings are you using on PuTTY? You should use 8N1 and baud of 115200bps.

    Do you have a "Stellaris Virtual Serial Port" installed in your Device Manager? If so, that is what you need to connect to.

    The enet_io example doesn't enumerate an additional COM port, it just sends PuTTY data through the same port as used for debug. I tested the example on my EK-TM4C1294XL LaunchPad and had no problems.
