Option to "reverse" function of RTS/CTS

[bycaldr]

Hello everyone, I have a exotic device that wrongly implements TTY->RS485 circuit and CTS/RTS needs to be set reversed-oposite way to process communication correctly. I tested it with simple script using libmodbus and when I used option modbus_rtu_set_rts(ctx, MODBUS_RTU_RTS_DOWN); communication worked correctly.

But my app is written in NodeJS and I'm already using modbus-serial which uses serialport. I spent some time on bindings-cpp and trying to update Baton classes but I wasn't even able to the dirty way reverse CTS/RTS vales.

Do you guys have idea or some advice on how would you address this?

Thank you!
