INPORT Function

X = INPORT(port)

Reads a byte from an I/O port and returns it (0–255).

Note

Only use on hardware that expects 8-bit port reads at that address.

How to read it

• Classic x86 port-mapped I/O (not MMIO).
• Often used for legacy controllers such as the PS/2 keyboard.

---

Examples

REM Read data from PS/2 controller
DATA = INPORT(&60)
PRINT DATA

Notes

• Always use the correct width for the target port.
• Continuous polling may stall the system; check status before reads if possible.
