Re: PID board with FIFOs

It seems that the driver doesn't use FIFOs, and you're trying to use FIFOs, right? I think there's no significant difference between 16550a and 16552. What parameters did you set for the chip? Have you already fixed the problem? Regards, -------------------------------------- Kenichi Aramaki Fujitsu LSI technology limited e-mail: aramaki@eng2.flt.fujitsu.co.jp Phone: +81-44-812-8068
