from the printer.
Pin 4 (RTS) is used to control the data flow to the printer, which raises RTS when it is ready to accept data
and lowers RTS under any of the following conditions:
Print buffer has less than 256 unused locations
Printer is out of paper
Printer is off-line (the select button <SLCT> on the front panel has been pressed)
Input to pin 5 (CTS) is monitored during data transmission from the printer. The unit transmits only if CTS is
