The flow control lines may oscillate if they are not tied down. This will cause a lot of unwanted modem status interrupts. I've seen interrupt rates of 30K/sec on single port (10K/sec in, 10K/sec out, 10K/sec for flapping modem control lines). The sio driver wants to have the modem status interrupt enabled almost all the time so as to be promptly informed about changes in carrier detect. -- Bruce Evans bde@kralizec.zeta.org.au
