Hi,

My question is about accessing PC hardware like serial com port from .net, C# environment.

Details:
Purpose: Up on button click, need to read a word file, and transfer the same to serial comm port char by char. Also how do i configure the serial Com port for baud rate, start bits, stop bits...etc from .net, c# environment.
Environment: GUI developed using .net and C#. Win7/winXP.
