Hi, AlexT_Intel,sorry,I should describe the situation in more detail.
Hardware: Intel@ Edison Board for Arduino
Why: There are two UART provided by the Board, one is TTL ,and the other is used for terminal console.I want to use the terminal console port as simple UART function,that's to say ------ sheild the terminal function.
==================================================================
In the link

It tells how to sheild the terminal fuction, but it did not work. When I run Serial2.begin(115200)
You can read the code (Serial2.begin(115200)) in arduino-windows-1.0.4(TTYUART.cpp),and understand what I want to describe.
Thank you
