Request/Release SLTA
This message may be used to grant ownership access of the SLTA-10 Adapter to any
node on the local network.
In a design where there may be more than one network
node that wishes to control the SLTA-10 Adapter’s connection states, Request/Release
provides a method of managing this control.
In this case a node will request the
SLTA-10 Adapter, and the response to this request will be successful (code Ox3D) if
access was granted, or failure (code OxlD) if it was denied. At the end of such a
session the node which was granted ownership must release the SLTA-10 Adapter,
allowing other nodes access to it.
This process only works if all nodes employ this
mechanism. The request state is not preserved across resets of the SLTA-10 Adapter.
typedef struct {
byte sub-code; // always #I
byte app-command; // value = 15
boolean req-rel;
// TRUE if request, FALSE if release
} ANM-request-slta-request;
Clear EEPROM Pool
This message will clear the entire EEPROM pool usage, and will remove the
following configurable strings. The strings will be set to null strings, not their default
values.
l Modem configuration string
l Hangup string
l Dial prefer string
l All dial-out directory entries
typedef struct {
byte sub-code; // always #I
byte app-command;
// value = 16
} ANM-clear-eepool-request;
Install NVConnect (NSI mode only)
This message writes the NVConnect byte. A value of OxFF (the default) will disable
this feature. When this feature is enabled, the SLTA-10 Adapter initiates a dial-out
when it receives a network variable update.
typedef struct {
byte sub-code;
// always #I
byte app-command;
// value = 17
byte NVConnect; // two 4-bit fields
) ANM-install-nvconnect;
