The mapping also creates the possibility of changing this modified printer into

a normal one by plugging in the special connector from the Protected Printer

example on page 51.

When port switching is enabled, the serial port is the only port with which the

printer can talk to itself. To make the printer talk to itself, a special serial

connector is required that connects the transmit data output to the receive

data input. Any form of handshaking for data transmission control should be

disabled. This can be accomplished by connecting pin 4 (RTS) to pin 5 (CTS)

and to connect pin 6 (DSR) to pin 8 (CD) and to pin 20 (DTR). Thus, when

one of the three front panel buttons is pressed, the printer receives a

message through the serial port sent out of that serial port by the same

printer.

The serial connector is displayed in Figure 52.
