connection through a ftdi ft232s usb to serial converter
Message 1 in thread
Hi all!
I wonder if anybody ever tried to connect to a serial device through usb
using the ft232r converter by ftdi (www.ftdichip.com) on a linux box in a
qt-application.
I compiled the module and my system finds the converter on ttyUSB0. So
what I need was the possiblity to change properties like buffering,
parity, flow-control, ... in a qt-application.
Is there allready some code to get such things to work? If not, could
anybody please point me to some documentation, where such things are
explained or to some example-code?
thanks in advance!
kind regards,
Andy

Why using ft232r in a Qt application as opposed to a non-Qt application
makes a difference?

I think he expects that Qt abstracts the serial control interfaces for
linux, windows, mac, etc.
He should be looking at tcgetattr/tcsetattr in linux man pages instead

I do not have tcgetattr or tcsetattr on my system (it´s an embedded linux
btw)
What I tried was using qextserialport with such a device. the thing is,
that this works with serial ports (/dev/ttySx) but not with my converter.
