i read the documentation for the serial console, its said that in most cases there
is a kernel recompilation needed to support serial drivers on the machine.
but i want to make the program as portable as possible.

unrelated to the serial console and the minicom driver, for that exists a userspace program minicom(1):(http://linux.about.com/library/cmd/blcmdl1_minicom.htm)

is there any other way to log something to a file while being in an interrupt?

any ideas would be great
thank you
