Sending and Receiving Data
After a connection is established, the Expand-over-NAM, Expand-over-ServerNet, or
Expand-over-FOX line-handler process periodically probes the subdevice to which it is
bound to ensure that the line is still operational. If the line-handler process does not
receive a response to its probe within a certain timeout period, it will retry the probe a
specified number of times. If the retry limit is reached before a response is received,
the line-handler process will declare the connection inoperable.
You can set the probe frequency rate, timeout period, and retry limit using the Expand
SCF attributes TIMERINACTIVITY, TIMERPROBE, and RETRYPROBE.
