Programming Via Escape Sequences
5–30
If multiple tone commands are to be sent in a string, a delay of at least 100
ms should be placed between each command to ensure that each tone occurs.
The approximate frequencies versus tone (n) are given below. Tones 1
through 12 form a rough chromatic scale.
