drivers and micro-controller ICs with refresh RAM, character
generator and interface logic. The high speed 8 bit parallel
interface is 5V TTL/CMOS compatible suitable for connection to
a host CPU bus. The asynchronous serial interface accepts
baud rates up to 38400, none parity. User defined characters
and many control commands are available.
