IF it is practice, an IF... THEN...
If it is a practical application, it should be, and the upper machine control LED lamp is not, VB.NET is a PC to control, as a player put up to 0000 0000 representatives, from VB.NET only responsible for the IO (COM/USB/RJ45) sends a 0000 0 0001 is open, the VB.NET is responsible for sending 1,
