Protocol determines what type of device or system is on the other end of a comm link.

Poll period determines how frequently controllers on a comm link are polled. It can range from 5 seconds to 24 hours.

Long Poll Period is for less frequently performed polling operations, determined by the protocol. For modem links with restricted bandwidth, it may be useful set this the same as poll period, to reduce costs.

Timeout determines how long to wait after a poll, if a response is not received, before communicaton will fail. For each poll, 2 retries will happen before the operation is aborted.

Idle Disconnect will cause the comm link to be disconnected after a period of inactivity. This can reduce charges for modem links. Setting this to zero disables this feature.

No Response Disconnect will cause the comm link to disconnect after no response is received from a poll for the specified time. Setting this to zero disables this feature.
