* v0.9 - thorough cleaning, URBification, almost a rewrite
* v0.10 - some more cleanups
* v0.11 - fixed flow control, read error doesn't stop reads
- * v0.12 - added TIOCM ioctls, added break handling, made struct acm kmalloced
+ * v0.12 - added TIOCM ioctls, added break handling, made struct acm
+ * kmalloced
* v0.13 - added termios, added hangup
* v0.14 - sized down struct acm
* v0.15 - fixed flow control again - characters could be lost
* Functions for ACM control messages.
