Yes, rtf_create_handler() is what I have done for both ttyS0 and ttyS1. I collect up enough bytes for a message and then send the data up a RTFIFO. I did (do) have one problem, I had a hardware error that caused lots of errors in the serial message. Each error, I sent a message up the FIFO. When I got a lot of errors and wrote a lot of messages up the FIFO, apparently overwriting it, the operating system crashes. > Or create a thread that just waits on rt_com_read()? > I need a server that also listens on the serial port, up to now I did it > in userspace with a signal handler that does nothing but copy data from > the com port to a buffer, but that seems to be not fast enough - only > ~19200bd on a 133Mhz embedded PC.
