More depressing fact is NetBSD/alpha does not utilize DMA assist for
Zilog SCC. The current implementation of NetBSD/alpha runs plain PIO
(like as most of other SCC). Worse than it, the implementation does not do the
right thing on the _paired_ SCCes for full modem control. To make all right,
it'd require full scratching of zs_ioasic.c code.
