rtl_request_traps() with rtai?

Hello Paolo,

Hmm, good question, I don't really know, since I don't use RTLinux. =8] 
 
The sourcecode, I am working with, AFAIK uses soft-interrupts for setting 
breakpoints. To install the needed breakpointhandler the RTLinux-version of
this 
sourcecode uses the function "rtl_request_traps". 
 
If I set a breakpoint in the RTAI-version, the running task is suspended
with the 
following message: 
 
 
Nov 25 11:36:15 tb10bhp kernel: Default Trap Handler: vector 3: Suspend RT
task 
D0D3E9C0 
 
 
Is there a way, to install an own Trap-Handler? 
 
Best regards, 
 
Hans-Peter Bock
