These characters are used to provide a reliable indication of the start of packet. They must not appear anywhere else in the body of the
message:
•
Controller-to-Target: This is the "<" character (ASCII code 60). It is also known as the "less than" character.
•
Target-to-Controller: This is the ">" character (ASCII code 62). It is also known as the "greater than" character.
5.3.5.2 Target Address
The Controller sends a packet with the address of a Target – the destination of the packet. When the Target responds,
the address used is the same address, to indicate to the Controller the source of the packet. The Controller does not
have its own address.
