PROBLEM: linux serial rs-232 bug when open()

[Dominik Wilczynski]

Hi,
 
I'm doing embedded development with rs-232 interface and I noticed a bug in
serial driver. When I open ttySx device, open() function returns 0 instead
of proper file descriptor. I have to perform open() twice before I get exact
file descriptor. 
 
Some guys were discussing similar bug:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0104.2/0830.html
 
I use kernel 2.6.11.4-20a-default on SUSE 9.3 disctribution. If you would
like to have more details on this, please let me know and I 'll send you
description of my configuration.
 
Best Regards,
