ABSTRACT:
A pair of stations are associated with each other so that a data frame is transmittable from either to the other, the data frame including as basic fields thereof a header field, a data field with a data sequence, and a frame check field. The former comprises a calculator for calculating a total length of the basic fields, as a basic length, and/or for calculating a current error rate, a controller depending on the basic length and/or the current error rate to make either of an affirmative decision for and a negative decision against sending a request for an acknowledgment of a reception of an entire length of the data frame by the latter, and a formatter for formatting the data sequence into the data frame, the formatter being responsive to the affirmative decision to combine the basic fields and a message field containing the request, to constitute the data frame.
