Dial modifier characters (except comma, colon, and L) in dial commands that initiate cellular
connections are ignored. Dial modifier characters in dial commands that are forwarded to an
attached dial-up modem are processed by the modem.
Use this command as you would for an ordinary analog modem. There are two cases:
1.
The dialing directory is searched for an entry containing the phone number
n
and a match is
). In this case, the legacy analog phone number (or any number of
your choosing) is translated into the Port number and IP address in the directory entry, and
used to create a TCP client connection to the remote TCP server (Listener).
Example:
ATD3456789
(The remote analog modem with this phone number was replaced by a Modemulator, and {Y
was used to translate the number to a Port/IPaddress)
Example:
ATDT4
was used to create an entry having the phone number 4, with the associated
Port/IPaddress of the new remote Modemulator)
This is equivalent to
ATD4
since the 'T' dial modifier is ignored.
2.
The dialing directory is searched for an entry containing the phone number
n
and a match is
not found. In this case, the entire AT command string is forwarded to the connected analog
modem (if present), and an ordinary analog modem connection is attempted. If no analog
modem is attached, the
NOT FOUND
message is displayed.
To forward only the dial string portion, but not the configuration commands, issue the
Example:
ATDT18005551234
(a remote analog modem's phone number)
The following commands are not forwarded to the analog modem:
$
(Help) commands
I
(Info) commands
{
(Modemulator-only) commands
&C0 (force DCD) command
A/
(repeat last command)
