Thanks for the reply, i understand and appreciate the efforts taken by people to help me, i just felt i had annoyed people in some way. :)
I managed to solve the sio.c stack problem, by putting a "don't accept till last sent" function in sio.c transmit part. sys_timeouts is still confusing me, but i've created another thread in the mailling list for it, so let me not add it here.
