Disable interrupts whilst checking for keys in OS_ReadC / INKEY
This ensures that on exit from OS_ReadC / INKEY either a character is returned or the input buffer is empty, and that Portable_Idle is only called when the input buffer is empty. This avoids a 10 microsecond delay and relying on timer interrupts to make progress and allows reliably waiting for input and another event by: Disable Interrupts Repeat Call INKEY(0), exit loop if key pressed Check other event, exit loop if key pressed Call Portable_Idle Version 6.42.
