6.2.5 Connection Sequence
When the dial command is received by the modem, all characters that are
extra to the number you are dialling are considered to be modifiers.
Invalid characters are ignored.
The modem connects to the telephone line. The setting of the X command
determines whether or not it attempts to detect a dialling tone. If it is set
to monitor the dialling tone (default), but detects nothing within the
timeout period, the call is cleared and the following message displayed:
NO DIALTONE
However, if the dial tone is detected successfully, or if the X command
setting does not require dial tone, the modem begins to dial the number.
If you press any key after a dial command is terminated by <CR> , the
modem abandons the call and displays the message:
ABORTED
(Note, however, that this feature can be disabled with the ''H command.)
When dialling is complete, the modem allows forty seconds to make a
connection, and monitors the telephone line for network tones.
When a call is successful, i.e. the remote modem's answer tone is detected,
the modem proceeds to exchange signals with the remote modem; a process
known as handshaking.
The modem verifies the call with the following response:
CONNECT
The connect response may also display the associated line speed, or
interface speed, according to the setting of the constant speed interface
command
&I .
If LAPM or MNP is enabled, the modem attempts to connect with error
correction enabled. If the handshake is successful, the modem displays an
appropriate message (see the
V
command). If the MNP handshake is not
successful, the modem normally transmits data without error correction.
(Refer also to the command
–E .)
