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.

Serial busy 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
