The serial monitor does not display messages

Hello

I cannot see the Serial message of sketchs, for example the sample sketch Running shell commands using Process class, by by Cristian Maglie and Tom Igoe.

I upload via WIFi, besides I am not able to upload via USB why or the port is in use or the IDE crash.

code or url of code?

Hello

I think is for I upload via WIFI, I.e. the port is occupied by Linino.
The last try is the datalogger example which, incidentally, does not write on the sd as prides himself on doing.

The crash occurs always when i find a not busy port.

It seem me there is a lack of documentation and significant examples.
