Command Processing
This section describes the structure of commands (in the form of ASCII
characters) from the DTE to the modem and replies from the modem to the
DTE. Other modem input signals that may command the modem to take some action
are covered in other sections.
Many modem parameters and some command memory are stored in user accessible
registers called S-registers. For example, S-register S3 contains the decimal
value of the <CR>character. S-register behaviors and definitions
are discussed in the S - Register section.
The carriage return, line feed, and back space characters are user-defined
by means of S-Registers. The symbols <CR>, <LF>,
and <BS>in this text represent the characters that are defined
to mean carriage return, line feed, and back space, respectively. If you
do not change their definitions, the three symbols are defined as the ASCII
characters CR, LF, and BS.
