Summary of Motion and Reconnect Thresholds

Table 3-6 provides summary information about the motion and

reconnect thresholds.

the CTS and the

initiator (initiator/buffer

transfers)

Minimum amount of

CTS reconnects to

the initiator and

accepts more data

Minimum amount of

data that must be in

the buffer before

the CTS reconnects

to the initiator and

transfers more data

If you feel that data transfers between a particular host and CTS need

to be fine-tuned, use the following rule-of-thumb to adjust the motion

or reconnect threshold:

If the data transfer rate is fast, raise the reconnect threshold.

If the data transfer rate is slow, raise the motion threshold.
