FT4232H -- RS232 Serial Use
« on: October 27, 2021, 05:15:34 PM »

I am on linux (Debian 10). 

I have a FT4232 configured like this:
-- Port A -- RS232
-- Port B -- I2C
-- Port C -- GPIO
-- Port D -- GPIO

I can see /dev/ttyUSB0 until I remove the modules using:
-- sudo rmmod ftdi_sio
-- sudo rmmod usbserial

I do this so I can use the linux driver libftd2xx

But when I remove the modules then the ttyUSB0 is now missing.

Is there anyway to send RS232 via the system (/dev/xxxx) or must I send/receive via api calls in software?

Thanks
