A process and system is provided for setting up a polling interval for a device
that sends a not acknowledged (NAK) signal. The process determines the number of
times the device sends a NAK signal before a successful data transfer; and also
determines a statistical parameter based on the number of times the NAK signal
is received before a successful data transfer; and sets a polling interval for
the device based on the statistical parameter. The statistical parameter may be
an average, median, maximum or minimum number of times the NAK signal is received
before successful data transfer. A polling interval may also be set based upon
the number times the NAK signal is received, wherein the polling interval increases
with the number of NAK signals. The polling interval may double after every NAK signal.
