Note that you could use function Do_IsDevice provided in system unit for this (if Input is redirected/piped, it is not a device, otherwise it uses the console device). However, I suspect that this function is only used internally and there's no way of directly accessing it outside the System unit. Nevertheless, you should be able to find proper implementation for all FPC supported platforms by looking at implementation of this function.
