Three bytes total: ack, status, reason.
ReadReadio is different from the other commands.

Most other responses have the 3 byte HEAD/ACK
followed by variant.
ReadRadio response has 0x02, followed by body.
Body is composed of header, pump data, CRC. Ignoring history
page commands, and focusing only on simple "read serial number" type
of commands, while the size, depends on the command, the average
response size is 78 bytes.
This is for the 14 byte header well, 13 byte header plus 64 bytes of
data plus CRC so 0x02, info, data, crc the length of the response is
encoded as the distance between the 14th byte and the CRC at the end
this value is stored in the 6th and 7th bytes of the response
EOD flag is also encoded in the 6th byte, masked against 0x80.
