Group or Subnet Table Clear
This message clears all entries in either the group or subnet forwarding table for
a single domain for a single router side. The message is segmented to cover eight
byte sections to prevent lengthy EEPROM write operations.
This message uses the Request-Response protocol. The configuration checksum
in EEPROM is updated.

unsigned group_or_subnet : 1; // 1 => Group, 0 => Subnet

Group or Subnet Table Download
This message configures the entire group or subnet forwarding table in EEPROM
for the specified domain for a single router side. The download function is
segmented into eight-byte sections.
The least significant bit (LSB) of the table field maps to the lowest subnet or
group ID in the current set of table entries defined by the index_times_8 field.
A value of ‘1’ specifies that forwarding be enabled for the corresponding group or
subnet; a value of ‘0’ disables forwarding. Subnet 0 is used for special protocol
functions and is never marked for forwarding.
This message uses the Request-Response protocol. The configuration checksum
in EEPROM is updated. Each byte in the table entry includes routing flags for
eight subnets or groups.
typedef struct {
unsigned group_or_subnet : 1; // 1 => Group, 0 => Subnet

unsigned unused : 4;
unsigned index_times_8 : 2;

Group Forward
This message sets the forwarding flag in the forwarding table for a given group in
the specified domain. If the
ram_or_eeprom
field is set, both the RAM and
