Re: [Ftdi-usb-sio-devel] latency on serial port

[Bill R. <bil...@gm...>]

Unfortunately strace doesn't decode the TIOCSSERIAL structure.

However setserial is not the right thing for this anyway. It's more for
traditional serial ports - ie not USB ones. It's a way to communicate with
the serial chip. The only use in the USB driver I've seen is to set
nonstandard baudrates.

stty is the correct program to use.

You have to set the VMIN/VTIME values (which stty calls time and min)

man termios

describes the ioctls stty uses.
