+=head1 BLUEBOX MODE
+
+A blue box is a phone phreaking device that generates tones (formerly)
+used for in-band signaling within the telephone network. B<soxdial>
+can generate these tones.
+
+To enable bluebox mode, use the B<-B>, B<--bluebox> option.
+
+Unlike touchtone dialling, bluebox signals have a timing
+specification. When entering bluebox mode, the digit time and
+inter-digit time are set to 60ms (except the kp and kp2 tones, which
+sound for 100ms).
+
+To exit bluebox mode, use the B<-N>, B<--normal> option. This resets
+the timing to whatever it was before entering bluebox mode.
+
+In bluebox mode, there is no letter-to-number conversion.
+
+The bluebox keypad has digits 0-9, which can be combined in a single
+dial string. The keys kp, kp2, st, st2, and st3 must appear alone
+as dial strings (meaning, put a space before and after them). The
+alternate names for 0 (10), st3 (11), and st2 (12) are not supported,
+since there's no way to tell an 11 from two 1's.
+
+See this Wikipedia article for more information on the blue box:
