serial port driver

["prasanna um" <pachu_um@hotmail.com>]

Hello all,

Kindly let me know if i need to send more details, than what is mentioned 
below

         I am a newbie in kernel programming.
I am learning how to write device drivers.
My present object is to write a small kernel mode driver, which will help me 
to communicate between two PC's using the serial port. I have read that i 
can do that from the user mode, using the existing serial port driver 
(serial.c). But since i want to learn the kernel concepts, i would like to 
write a kernel mode driver which does the same.

I am still at the begining of it, but i have some basic doubts. I would like 
to know how to trigger the interrupt on the serial port ( i have registered 
interrupt 4) and selected 0x02f8 - 0x02ff as the resources. I have enabled 
the interrupt by writing 0x07 to 0x02f9. But when i write a character to the 
0x02f8, i do my interrupt handler is not getting accesed. I am not sure how 
to proceed. Kindly suggest

best regards
pachu
