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).

Abstract: The remote unit (113) maintains a count of inserted blank scan lines generated by the remote unit (113) and uses this to maintain a fixed number of scan lines per page during facsimile transmission. More particularly, in the preferred embodiment of the present invention the remote unit (113) maintains a fixed number of lines per page by deleting scan lines comprising a predetermined set of characters from the actual facsimile transmitted, until the number of scan lines deleted from the facsimile is equal to the number of blank scan lines generated by the remote unit (113).
