Hello,

I am a beginner at using PICs and would like to do some RS232,422,485
communications.  Not sure exactly which one yet but eventually I imagine
all.  I would like to create some programs using visual basic or visual
c++.

(1st ?)What is the command for reading and writing data to and from the
data bus of my PC in Visual C++ or Visual Basic?  Do both of these
softwares do this?

(2nd ?)What addresses does a person access in order to do standard RS232
communication.  Read Address?  Write Address?
