I was in the industry in the 90's.

The cash drawer used a telephone line that was RS232, just 6 wires I think.
2/3 and 7 for transmit and receive.

We opened the port and sent several chars to the drawer back then. The draw would check the char and actuate the solenoid. I don't remember the char code or code sequence. but I think it was all the same. Like 1 company in China made all the solenoids.

Program the port, 9600,N8P
Open the port,
check drawer status
send the code sequence if closed
check drawer status
close the port.
