I good explanation in the June 98 issue of Linux Journal. In Understanding /dev, Preston F. Crow (he, pretty cool name ;) add a column about Serial Port Device and why callout device became obsolete. Lots of people used ttyS for both incoming and outgoing communication but only lock the ttyS device and not it's cua counter part. Removing cua will just make it less confused. Callout device are just there for historical compatibility.
A pointer to some mailing list archive are also give: http://www.uwsg.indiana.edu/hypermail/linux/kernel/9607.0/0363.html
Hope this help.
