Accessing hardware registers can cause your system to crash, data to be lost, or damage to your hardware. TransEra cannot be held responsible for any consequences.
The READIO and WRITEIO statements allow an HTBasic program to directly manipulate the interface hardware and physical memory locations. The hardware register numbers and their definitions are dependent on the actual hardware. The level of access to the computer hardware is also dependent on operating system protection methods. Do not mix READIO and WRITEIO operations with STATUS and CONTROL operations. In general, you are better off using STATUS and CONTROL operations and avoiding READIO and WRITEIO.
