I see the ttyUSB0 - device and I tried to work with it, just like ttySx. |
| 29 |
the strange thing is, that after a very short period, the application |
| 30 |
running on the embedded board seems to not get any more data from the |
| 31 |
device. I guess, this is due to buffering things or so. That´s why I asked |
| 32 |
for some code or header file to be included, to set the correct values. I |
| 33 |
have to port a qt-application to the system. The application itself works |
| 34 |
on windows as well as linux and on the embedded board. But on windows, one |
| 35 |
has to set the properties of the usb-device through the driver. That´s why |
| 36 |
I asked for code, on how to do this on linux. |
