Abstract
Improved means and methods are provided for transmitting binary data on a communication system, such as E-mail, which restricts the number of acceptable characters that can be transmitted. In a preferred embodiment, the binary data to be transmitted is first subjected to a Welch compression and then converted into base-85 digits for transmission. At the receiving end, the received base-85 digits are converted back into compressed binary and then subjected to Welch decompression to obtain the original binary data.
