Hello akiyama-san.  It is Warner.  Long time since I've spoken with
you. :-)

This is a no-op in current.  Have you tested it in 4.x?  I think it is
right from what I recall about 4.x, but this stuff has always been
black magic to me.  I think the other changes look OK, but haven't
tested them with my serial adapter or my umodem phone.

Warner
