THE SERIAL PROTOCOLS
This printer has four serial protocols selected by DIP
switches 3 and 4. Figure G-1 shows a typical byte of serial data
and Figure G-2 shows timing charts for the 4 protocols.

In the serial busy protocols, this printer uses DTR (pin 20)and
RCH (pin 11) to signal to the computer when it is able to accept
