I'd like to know how to read and write to I/O-ports in the computer using
Visual Basic. I'm looking for a small routine that works like PEEK and POKE in
the old Commodore machines or the IN and OUT instructions using assembler
on the PC. I'm experimenting with electronics and plan to build an I/O-card
with the old 8255-chip to control my electronics on the lab bench.
