Parameter
1. This command may be aborted generally by receiving an
ATH
command or a character during
execution. The aborting is not possible during some states of connection establishment such as
handshaking.
2. Parameter "I" and "i" only if no *# code is within the dial string.

ATX

.
4. <n> is default value for last number that can be dialed by
ATDL
.
5. Responses returned after dialing with
ATD
.
For voice call two different responses mode can be determined. TA returns
“OK” immediately either
after dialing was completed or after the call was established. The setting is controlled by
AT+COLP
.
Factory default is
AT+COLP
=0, which causes the TA to return
“OK” immediately after dialing was
completed, otherwise TA will return
“OK”, “BUSY”, “NO DIAL TONE”, or “NO CARRIER”.
6. Using
ATD
during an active voice call:
When a user originates a second voice call while there is already an active voice call, the first
call will be automatically put on hold.
The current states of all calls can be easily checked at any time by using the AT+CLCC
command.
