If a command string is to be forwarded to the analog modem, any of the above commands should
be grouped at the end of the configuration commands, and before the Dial command, if present.
DL
Dial Last Number
This must be the last command in the AT command string.
Redial the last phone number attempted. It proceeds as in the cases described in the Dn or D:
commands.
DSn Dial Stored Number
Since the 'S' in ATDSn is ignored as a non-implemented dial modifier, Dial Stored Number
commands can be emulated. The USRobotics Courier analog modem allows stored numbers in
locations 0 through 79, so to emulate a stored phone number with the Modemulator, simply assign
a phone number in the Modemulator dialing directory equal to the legacy storage location index.
Example:
AT{Y=2::172.17.2.1
(Stores the phone number 2, the default port number, and the IP address into the
Modemulator dialing directory)
ATDS2
(Dials the stored number 2, where 2 was formerly the location of the stored number
in the analog modem)
D:i:p Direct IP Dialing (i=destination IP address, p=destination port number)
This must be the last command in the AT command string.
Bypass the directory lookup, and attempt to create the TCP client connection directly, using the IP
address and port number supplied in the command.
Separate the ATD, IP address, and Port number with ':' (colon) characters.
Example:
ATD:172.17.2.1:2025
If using the default Listener port number (8888) on the answering Modemulator, you may
optionally omit the port number.
Example:
ATD:172.17.2.1
One advantage of using direct IP dialing is that it doesn't use the dialing directory, so the number
of remotes is unlimited. The dialing directory is limited to 7200 entries.
E0 * Command Echo OFF
Disable local echo of typed characters.
