Install Dial Prefix

The default setting for this string is "ATDT". This string is sent as a prefix for any

dial-out operations. This particular sequence instructs the modem to dial using

Touch-Tone (DTMF) signaling. If pulse dialing is required, the prefer should be set to

"ATDP."

typedef struct {

byte sub-code; // always #I

byte app-command; // value = 12

byte total-size; // of the data string

byte offset;

// for incremental writes

char dpre-string[];

1 ANM-install-dpre-request;

This message uses the EEPROM pool to store the dial prefix.

See the section on

EEPROM String Pool Management above for details.

Install Hangup Timer

The hangup timer is controlled by an eight bit value in EEPROM.

The default

setting for this value is zero, which results in no hangup timer action.

If the hangup

timer is a non-zero value, the SLTA-10 Adapter will hang-up and break a connection

(if in the

CONNECTED

state) when the number of minutes specified by

timer-value

have elapsed and no uplink or downlink activity has occurred. The default value for

this timeout is zero, meaning that the phone connection will remain active

indefinitely, even if there is no activity on the link.

typedef struct {

byte sub-code; // always #I

byte app-command; // value = 13

byte timer-value;

} ANM-install-hangt-request;

Configure Modem

This message will cause the SLTA-10 Adapter to send its Modem Configuration

String to the modem provided it is not in the CONNECTED state. See the Install

Modem Configuration String message for further details. If the modem is in the

CONNECTED state, the failed status will be returned.

typedef struct {

byte sub-code;

// always #I

byte app-command;

// value = 14

1 ANM-modem-config-request;
