Dialing Out for Internal Fax/Modem
Using the “M” command following the “ATD” will tell your omni.net LCD+M to automatically
switch calls to the internal fax/modem once dialing is complete.
Type: ATDM17146930762<enter>
Manually Switching Communication Modes
The manual switching functions will only be necessary if your communication software does not
allow you to change your dial-up string.
Conventional dialing commands: ATD, ATDT and ATDP, used by most existing communication
software, can be mapped onto one of the new dialing commands according to the AT&O setting as
follows:
AT Command
Dial string it will map to
AT&O0
ATD, ATDT and ATDP are the same as ATDM
AT&O1
Auto-selection of 64kbps and 3.1 kHz on outgoing calls
AT&O2
ATD, ATDT and ATDP are the same as ATDI
AT&O3
ATD, ATDT and ATDP are the same as ATDA
Table 56. AT Command for Conventional dialing commands
The factory default is
AT&O2
. This means the modem will select ISDN data mode when you do
not specify which communication mode to use in your dial command (i.e. ATD or ATDT).
ATDMs
This command directs the modem to go on-line, dial according to the string entered and attempt to
establish a connection.
If +FCLASS=0 is selected, the modem will behave as a data modem and will attempt to connect to
another data modem. The modem will have up to the period of time specified by register S7 to wait
for a connect. If this time expires before the modem can connect, the modem will go on-hook with
the NO CARRIER response. This command will be aborted in progress upon receipt of any DTE
