Looks like something different?
What I was looking for is to execute the ftdi_open (with the actual tty struct) when getty opens the device. If the open_count is already 1 (from console) then that does not happen. There may be some initialization missed there that is causing the read problem. Such as setting the low_latency flag (controls how received data is passed to line discipline), which is only done if ftdi_open is called with a real tty struct. -- Paul ------------------------------------------------------- Using Tomcat but need to do more?
