The big benefit for DH11 and DMF32 and 3rd-party DH11 work-alikes (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.
