Add alpha specific driver dir and man pages for serial devices. There's
a lot that needs to be added here and much of it can be based on the
i386 and pmax man4's.

This feature of the ioctl asic is not +yet supported. +.Pp +The mapping from device-special files (major and minor number) to chip +and port is arguably backwards. |
