C.5.1 Start of Packet

Controller-to-Target: This is the character ‘<’ (ASCII code 60).

Target-to-Controller: This is the character ‘>’ (ASCII code 62).

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. The only exceptions are in command RMS and CMS where the response is “FWPWR=<19.0”.
