The big benefit for DH11 and DMF32 and 3rd-party DH11
(Emulex CS-21...) is that since under normal workflow, many times more
chars go out than come in so DMA-out saves a lot of overhead when
blasting screens of stuff (like refreshing your page in EDT...) and
people don't type all that fast by comparison.
One question arises: how does that work with XON/XOFF flow control? Does
the DH11 handle that on-board? I mean, a VT100 for example is a very slow
device. It doesn't reliably work without flow control. You can't send a
page full of text, even worse with some escape control characters, without
it dropping large chunks of data.
