The A2232 has a 3.56 MHz 4502 (enhanced 65C02 compatible CPU) on board.  This
CPU handles all interrupts from the serial chips and manages RAM buffers for
each chip.  It drastically cuts down on the main Amiga CPU overhead for serial
ports.  The one advantage of the ASDG board is that it's capable of MIDI
speeds, while the Commodore board tops out at 19.2k Baud (with one weird
high speed mode at around 100k Baud).
