Abstract
A data telecommunications system and method is provided for sending a data stream of characters in distinct data packets between two units of data terminal equipment (which can be either terminals and/or computers) connected over communication lines. A modem is connected between each unit of data terminal equipment and the communication lines, and one initiating modem includes a means for changing the packet size of the data which is transmitted. The receiving modem checks the packets for errors, and if errors are found, the packet is retransmitted. The initiating modem counts the number of transmissions of data packets as well as the number of retransmissions of data packets. A ratio of retransmissions to transmissions is used to determine the optimum packet size. The packet size is continually subject to change as the ratio changes during transmission.
