OUT port, byte

OUT port, byte

Description:

This command sends a byte value to the specified machine I/O port. The use of this command inside Windows is considered to be only for those in the know. Windows provides no method of ensuring that more than one application will not access any I/O port at a time, so use this command with care (you know who you are).

If you will be distributing your application, and it uses INP() and/or OUT to control hardware ports, you will need to distribute and install certain files on your user's system. For detailed information, see Port I/O.

Note: Port I/O is not the same thing at serial port communications, but is usually used for programming the parallel port and other custom hardware devices. Please visit OPEN "COMn:..." for details on serial communications in Liberty BASIC.
