55 * cause a delay in the output but will not necessarily suspend the

57 * this is not a usable substitute. It causes a pause in the displayed
58 * output, for example, for the eye wink in snake. It is disrecommended
59 * for "delay" to be much more than 1/2 second, especially at high
60 * baud rates, because of all the characters it will output. Note
61 * that due to system delays, the actual pause could be even more.
