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
