At 9600 baud, you can get a lot of characters in the input silo of a DH or DZ before you service the interrupt, and sending an XOFF for every one of these input characters is silly. And running at 9600 baud is quite reasonable - ABLE DHDM's have a 256-byte input silo, so you almost never lose anything.
