Software-based compression is different from the modem-based
compression features that were presented in Chapter 23, “Asynchronous Connections.” By selecting
this option, you can improve throughput by enabling compression, but this depends on the
type of data and equipment you use. By compressing with software, you are substituting a repetitious
series of characters to reduce the amount of bandwidth required. When decompressing, the
compressed data stream is translated back into an uncompressed form.
