Certain SLTA-10 Adapter network management messages which are designed to
send a command string directly to the modem will fail if the connection status is
CONNECTED. This applies to the following messages: Send Modem String, Dial From
Directory, and Configure Modem. The telephone connection must be broken and the
SLTA-10 Adapter returned to the IDLE state for these messages to be issued.
Many of these network management messages, for example the “Install...” messages,
may be sent to the SLTA-10 Adapter from the host computer via the telephone link if
the SLTA-10 Adapter is in the CONNECTED state. In this case, they should be sent
using the niNETMGMT network interface command so that they are addressed to the
SLTA-10 Adapter itself.
Structures are defined in the file SLTA-ANM . H for each of the application commands,
and include the sub-code and app-command fields, as well as any additional
parameters for the specific application command. If the response contains data other
than the response code, a structure for the returned data is also defined.
EEPROM String Pool Management
The SLTA-10 Adapter’s EEPROM is used to store a number of varying-length
configurable strings which are used to control the modem. These strings can be set by
sending network management messages to the SLTA-10 Adapter, either from the
modem side or the network side. Since the strings are varying in length and the
EEPROM space is limited, a pool management system is used to optimize the usage
of EEPROM. The SLTA-10 MIP mode EEPROM string pool and the SLTA-10
NSI mode EEPROM pool are different! Changing the mode DIP switch and
cycling power will destroy the EEPROM pool.
For the SLTA-10 MIP mode, the EEPROM pool consists of the following strings:
l Up to eight dial-out directory entries. These may be used by index to initiate a
dial-out connection, and may contain any combination of AT commands and
numbers.
l One modem initialization string. This string is used to initialize the modem as
required.
