If you would like to know more about viewing, saving, and
reloading factory settings, refer to the following commands in
Chapter 4: &V (Result Codes Format), &W (Write/Save), &F
(Select Factory Default), and Z (Reset and Load Active).
Operating Modes (Command
and Data)
Before a modem goes online (establishes a successful
connection with a remote modem), it is considered to be in
Command mode, an idle state where you can modify its
operating parameters or issue modem commands. (Any
command issued is acknowledged with a response in either
words or digits. These are known as a result code and are
listed in Appendix C.)
Once the modems are online, either by answering or originating
a call, they automatically switch to Data mode. Data mode is a
state where any entries made from the computer are considered
data and are transmitted and received between modems. The
modems remain in Data mode until the connection is broken
with a disconnect or until they are forced into online Command
mode using the escape sequence (+++).
Switching Between Data Mode and
Online Command Mode Using the
Escape Sequence
The escape sequence allows you to exit Data mode and enter
online Command mode while maintaining a connection with the
remote modem. It consists of three consecutive plus (+)
characters and is only valid when the KeepInTouch Card modem
is online and in Data mode.
To enter online Command mode while in Data mode, enter the
following sequence:
TYPE: +++
The value of the escape sequence character (+++) and
the idle time required before and after an escape
sequence are determined by the S2 and S12 registers. If
you want to change these values, refer to Table 4-1 in
Chapter 4.
