When you use CRT, it's best to use the Delay procedure (millisecond
resolution) from this unit.
Otherwise, the GPC unit has Sleep (seconds) and SleepMicroSeconds,
but they don't know about CRT, i.e., you might have to call
CRTUpdate before using them, so output is flushed.
If you need to wait conditionally (e.g., until input becomes
available), you can use IOSelect or IOSelectRead (unit GPC), but you
might also need CRTUpdate.

Unfortunately, none of these are ISO Pascal -- it doesn't have any
timer routines. And the CRT unit is not ISO either.
