Simple Serial Communication Utilities

As an Electronic Engineer I've worked with many languages and for some diferents plattforms including desktop and embedded systems.
My natural envirovment is C/C++, but I've worked with Java, C# and hardware oriented languages (VHDL, Verilog).
I really like programing and always I'm looking for some ideas to development.
I add to the opensource philosophy do I try to share my knowledge with other people.

Now I am developing embedded systems for nuclear industries in the Argentina most important technology Company.
