Structure of a data packet with the home protocol

The home protocol can only be used in ekey home systems. Data packets are created for each
recognized finger and every time a refusal takes place at the finger scanner. The data fields within
the data packet are ASCII-encoded. This protocol has the following structure:
Data field Number
name of digits
PACKET TYPE 1
USER ID 4
FINGER ID 1
SERIAL NO. 14
FS
ACTION 1
RELAY 1
