Hello all,

I want to write 2 very small and simple applications
which run on two different computers and talk with each other
through the USB port of the PC, the first application will be the
Master and can send any one of the 3 following commands through
the USB port -

(in Hex)

A5 1 5A (option 1)

A5 2 5A (option 2)

A5 3 5A (option 3)

If the application on the other PC (which is the Slave) get
command 1 it will (for example) display "1" on the screen and
send back (through the USB) the following respond -

A5 11 5A

at the same way for command 2 it will display "2" on the screen
and send back the reply -

A5 22 5A


and for command 3 it will display "3" on the screen
and send back the reply -

A5 33 5A

I'm using Builder C++ 4, what do i need for start doing
something simple as that? also, how do i tell the PC which one
of it's (several) USB ports to use?

One small code example will help also,

Thanks very much,
Ramy
