serialportlowlatency

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

rust 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

rust 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();
