ITEM
DESCRIPTION
Initialization method
Default - when data stream is established, the module will be initialized to a well-known, safe configuration
appropriate for CSD connection. These include the following AT commands:
ATE1 - enable echo
ATQ0 - disable quiet mode
ATV1 - enable verbose mode
AT&D2 - DTR line inactive disconnects the calls
AT&S1 - DSR becomes active in data mode, and off in command mode
AT&C1 - CD becomes active when call is connected
Hardware flow control is enabled on the module
User: no pre-defined commands are sent to the module. Custom initialization can be done using "Additional AT
init commands"
Additional AT initialization
commands
These commands are sent after default commands (if default method is used). For example, to change DTR
operation to enter online command mode instead of default disconnect, use the following command: AT&D1
with "Default" initialization method.
Inactivity timeout
If a non-zero value is entered and the router detects an inactivity period in an established CSD call in excess of
the number of minutes entered, the CSD call will be automatically terminated. Note: data sent in any direction
will prevent the call from being disconnected. The specified value should be in minutes.

TCP connect-on-demand endpoint
The TCP connect-on-demand endpoint allows data to be buffered and then sent to a TCP server when the buffer has been filled. It
is primarily useful in situations where you do not want ‘keep alive’ packets to keep the socket open and create an overhead w
hen
the TCP data connection is not in use.
