Definitions for "Retries"
The number of times the polling/timeout process will repeat. Specifying multiple retries helps overcome information dropped due to network traffic and network latency.
If a device is attempting to communicate over a channel, but the receiver at the other end signals back that the data was corrupt, the sender then "retries" the transmission. Constant retries due to bad connection will eat away at otherwise good throughput specifications.
A communication port property that sets the number of times one device tries to communicate with another, before timing out.
