signals from interrupt

[Ofer Rashuk]

I am running MontaVista hardhat 2.4.2. linux kernel on a MPC8240 cpu with
a pci bus,NVRAM device ,64M ram and 32M rom (flash).
basically my application is running very well i have created all the threads
i needed and all other initialization are almost done.
the last problem i have regards interrupts.
on my target i have a dual UART 16550 device, one of it's ports used by the
kernel (kprintf,etc...) the other port i need to use for my own application.
in order to use it i need to receive an interrupt (mean RX interrupt), now
since there are no interrupts available out side of the kernel i thought of
using signals.
what i wanted to do is to get the interrupt with in the kernel and to send a
signal to the application, the problem is that every method i tried to
implement that did not succeed, can any body help me dealing with this
issue.

thanks in advance.
