poll the device for data?
The source is provided with ADT. I would guess that for it to be interrupt driven the interrupt driver just have to be fast enough to handle each received byte (86.8�s if "8N1"). ADT is polling. 

look at adt.asm in the ADTssc directory in the zip, look for PUTC and GETC.


BTW, polling is always faster than interrupts if all that is going on
is a data transfer.  When moving data at speeds so close to the limit
of what a machine can do, things should be kept as simple as possible.
