Why is my Ethernet serial connection timing out or not responding fast enough?


By default, SeaLINK Ethernet serial servers use Nagle’s algorithm to reduce network traffic and increase serial data throughput, with the side effect of increasing latency. Both SeaLINK devices and the virtual COM port driver have settings to disable Nagle’s algorithm, also referred to as “nagling”. To reduce latency, disable Nagle’s algorithm in both the SeaLINK device and driver.
