serialport_low_latency
FTDI serial communication chips support a low latency mode where the latency timer is reduced to 1 ms. This package allows enabling and disabling this low latency mode on Linux via the TIOCSSERIAL ioctl.
Examples
Open a serial port and enable low latency mode
use std::time::Duration;
use serialport_low_latency::enable_low_latency;
let mut port = serialport::new("/dev/ttyUSB0", 115_200)
.timeout(Duration::from_millis(10))
.open_native().expect("Failed to open port");
enable_low_latency(&mut port).unwrap();
Open a serial port and disable low latency mode
use std::time::Duration;
use serialport_low_latency::disable_low_latency;
let mut port = serialport::new("/dev/ttyUSB0", 115_200)
.timeout(Duration::from_millis(10))
.open_native().expect("Failed to open port");
disable_low_latency(&mut port).unwrap();
