Why did my application time out with a serial ENET interface?

Why did my application work with a plug-in interface but times out with a serial ENET interface?

Because the serial device server is a network device, it is dependent on network conditions for timely communications. An unpredictable delay is associated with using the remote serial ports. Applications may require longer serial timeouts to compensate for this delay. However, different applications handle serial timeouts differently, and each must be adjusted individually to account for your network conditions.
