You must press ENTER to send the command to the modem. Any time
the modem receives a command, it sends a response known as a
result
code
. The most common result codes are
OK
,
ERROR
, and the
CON-
NECT
messages that the modem sends to the computer when it is con-
necting to another modem. For a table of valid result codes, see “Result
Codes” at the end of this chapter.
You can issue several commands in one line, in what is called a com-
mand
string
. The command string begins with AT and ends when you
press ENTER. Spaces to separate the commands are optional; they are
ignored by the command interpreter. The most familiar command string
is the
initialization string
, which is used to configure the modem when it
is turned on or reset, or when your communications software calls an-
other modem.
