I have a PC, so dmesg said serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A How I said, I just handle RTS but from userland. This means a big latency between RTS activation and begin out data. I want only reduce this latency activating RTS on driver. My question is, is this *protocol* implemented actually or I must implement them. Thank you very munch.
