[gentoo-embedded] ftdi ft232r programming howto

[andreas . sumper]

Hi list!

Has anybody ever tried to communicate through a ft232r, which is a usb to rs232 converter?
I read through the documentation of ftdi (www.ftdichip.com) but all I found, was the documentation for windows.
I want to make this converter work on an embedded linux box, running a 2.6.14 kernel, including the module (ftdi_sio)
I see the device (/dev/ttyUSB0) but, how can I configure it (buffers, transfer speed, ...) and how can I read from the device and write to the device.

Could anybody give me some advice on where to start or did anybody write some piece of code, which works with such a converter?

Thanks in advance!

Kind regards,
Andy
