AT%C Compression Control
Data compression is a technique used to reduce the size of data being transmitted without losing
any of the original information.
Compressed data must be decoded at the receiving end of the communications path in order to
extract the original information.
Full details on the subject of data compression can be found in the Error Correction Section of
this guide.
