RS232C Interface Signals
Ready/Busy Flow Control
Ready/Busy is the hardware flow control for the serial interface on the CL608e/CL612e
printers. By raising/lowering the voltage level on Pin 20 of the RS232 port, the printer
notifies the host when it is ready to receive data. Pin 4 (RTS) and pin 20 (DTR) are the
important signals on the printer for this method of flow control. The host must be capable
of supporting this flow control method for it to function properly.
