RE: [Paparazzi-devel] Re: karmic ftdi serial issue

[mark.griffin]

I updated Ubuntu from version 9.04 (Jaunty) to 9.10 (Karmic) using the Update Manager application and observed the same error message.

I then updated the FTDI drivers and the problem went away; it no longer exists. FYI

Poine, your solution seems to solve the problem for me. Do I commit 
this code or will it break something for everybody else ?

Hi,

I don't remember where these lines are coming from.

I can't do the tests: I don't get any problems on my freshly installed karmic :-(

 int fd = open(String_val(device), O_RDWR);

could someone see if replacing with

int fd = open(String_val(device), O_RDWR|O_NONBLOCK);

would fix the problem ?

Pascal, any reason for opening serial ports in blocking mode ?
