Abstract

The present invention is for transmitting facsimile data over a wireless interface in a manner that minimizes the occurrence of time outs caused by wireless interface data corruption. Facsimile data to be transmitted over a wireless interface is collected and then transmitted using a wireless error detecting and correcting protocol (76). The facsimile data is re-transmitted if the data transmission is unsuccessful until the transmitting of the facsimile data is successful. Highly correlated lines in the collected facsimile data are identified if delays caused by the re-transmitting of the collected facsimile data reach a predetermined limit, and certain ones of the highly correlated lines that have a minimal impact on received facsimile data are then deleted to prevent a facsimile protocol time out (84).
