What steps will reproduce the bug?
const serialPort = new SerialPort({path:'xxx', baudRate:230400});
serialPort.update({baudRate:460800}, (err)=>{console.log(err)});What happens?
Received error in callback, the detailed information is:
Error: Error: Invalid argument calling ioctl(.., IOSSIOSPEED, -1 )
What should have happened?
I have read the source code, I think it is due to the ToBaudConstant method in bindings-cpp/src/serialport_unix.cpp. It will convert the baudrate passed by user. For baudrate higher than 230400, it will convert to -1 on MacOS.
I have also tested on windows, no such issue.
