serial port programming

[Marc Brünink]

Hi,

I've an application which uses /dev/ttyS3 to read and write some data. 
This software is kind of alpha. Sometimes it segfaults. So the serial 
port is not closed correctly. If I restart the application after a 
segfault I'm not able to open the port again. I've to reboot. Im 
wondering if it's possible to reset the serial port somehow. I mean: If 
I sent a SIGKILL it'll result in the same behavior. And I should be 
able to sent a SIGKILL to an application which uses the serial port, 
shouldn't I?

regards
Marc
