Serial issues (USB) RPI

I have a Serial Port (Via USB serial Emulator FTDI) working well in Windows environment and it compiles and runs ok. 9600 & 115200 Baud is working on different products but when i compile to the RPI 3B+ the 9600 seems to work but i cannot get any response from the 115200 product. I read that it may be something to do with the core freq and have tried adding the core_freq 250 line to the boot config.txt but it makes no difference.

Any ideas?

Sorted it. It seems to be the way the port baud rate is set in my application. The Win version accepts it but the RPI does not. Just copied the port opening procedure from demo and it works. so happy days
