If a character is available to be read from file within the time (in microseconds) indicated by timeout, WaitForChar() returns -1 (True). If a character is available, you can use Read() to read it. Note that WaitForChar() is only valid when the I/O stream is connected to a virtual terminal device. If a character is not available within timeout, a 0 (False) is returned.
