Use a UART (Universal Asynchronous Receiver Transmitter) such as the
General Instrument AY-5-1013A, $2.95 at Jameco.  A UART converts the
RS232 serial signal to parallel.  You might also need an LM1489 Line
receiver to protect the UART input against +-12 voltages.
This UART has the advantage of being easier to connect without a
microprocessor since the control lines come out on its 40 pins.
Actually, I haven't used this chip...  I seem to have bought one
without getting a pinout.

I don't know what handshaking signals Centronics requires.

Does anyone have a pinout for an AY-5-1013A UART?  I don't have a GI
databook nor can I find a second source, and IC Master (for four years)
has it listed, but doesn't have an advertisement.
