RegNo 2: PNETTraffic

Record
	ReceivedPackets:	LongInteger;
	SentPackets:	LongInteger;
End;

ReceivedPackets

This field holds the number of TCP packets received from the Ethernet.

SentPackets

This field holds the number of TCP packets sent from this node.

RegNo 10: Connections


Connection: Record		(* Factory setting *)
	PNETNo: byte;	(* 0 *)
	SerialNo;	(* 0 *)
End;

PNETNo

PnetNo is not used, and will hold the value 0.

SerialNo

The SerialNo field holds the Serial number of the connected device.

RegNo 11: TimeStamps

	LastConnectionAttempt:	RealDate;
	LastSuccessfullConnection:	RealDate:
	LastTXActivity:	RealDate:
	LastRXActivity:	RealDate:

LastConnectionAttempt show when a connection attempt was last made to this TCP node.

LastSuccessfullConnection show when a connection was last established successfully.

LastTXActivity show when data was last send to a connected PD 664.

LastRXActivity show when data was last received from a connected PD 664.

RegNo 12: Password

Password: Array[0..15] of byte;

(* 0 *)

Passwords

The Password field holds the password for the connected GPRS Device. The password is used as a key for the crypto algorithm. When a request is received, the TCP node uses the password to decrypt or encrypt the PNET-packet.

RegNo 14: GUID

GUID:

String[22];

Each channel type is identified by means of a unique GUID. The value of GUID for the channel is: PD/551304-01.
