Below is code snippet from program I got from ex-coworker. It's to do serial port tx/rx for verifying serial port. Now, I've got a request to add cts/rts control on the test. What are the parameter(s) I should add to control string "9600,n,8,1,n"?

JavaScript

this.serialService = GREUtils.XPCOM.getService("@firich.com.tw/serial_port_control_win;1", "nsISerialPortControlWin");
// ......
  rv = serialService.openPort(comport, "9600,n,8,1,n");

I changed "9600,n,8,1,n" to "9600,n,8,1,h" and it works fine, able to test cts/rts & dtr/dsr. The last character of "9600,n,8,1,n" is used to turn on/off H/W flow controls, including cts/rts & dtr/dsr. 'n' means no control, 'h' means HW controls ON.
