2.2.3 Firmware Upgrade
When POE Clock receives a TCP packet that has the first character colon ‘:’, 0x3a, it enters a mode
that expects firmware upgrade data consisting of an Intel Hex file. Hex load records may be blocked
to a maximum packet size of less than 1Kbytes.
Each load packet is acknowledged with a response indicating the last accepted load address. Lack
of a response indicates bad load data or failure to commit the load data to internal FLASH. Retry the
load packet a finite number of times.
