5.1.4.1 Start of Packet

Because this is used to provide a reliable indication of the start of packet, these two characters may not appear anywhere else within the
body of the message:
 Controller-to-Target: This is 'less-than' the character '<' (ASCII code 60).
 Target-to-Controller: This is the 'greater-than' character '>' (ASCII code 62).

5.1.4.2 Target Address

Up to 9,999 devices can be uniquely addressed. In EIA-232 applications this value is set to 0. In EIA-485 applications, the permissible
range of values is 1 to 9999.
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.
