8.8 "^AE" RESPONSE FORMAT

The meter's response to "^AE[nn]<CR>" is 4 bytes of data, sent as 8 HEX-ASCII
characters, followed by a carriage return (no other characters even when programmed
to echo). These four bytes are:
1: Serial Recognition Character below; e.g., "*", sent HEX-ASCII "2A")
2: Device ID (INF-B)
3: Bus Format Byte ("bUS.FMt"; e.g., HEX-ASCII "5C" for multipoint mode with echo)
4: Serial Communications Configuration Byte ("COMM": e.g., HEX-ASCII "56" for
2 stop bits, even parity, and 19200 baud)

8.9 EXAMPLES:

The following are examples of the different commands and their proper responses from
meters. For the following examples assume that:
a) echo mode
b) "*" as the recognition character of the meter
c) meter's address is "15 HEX" if it is used in the multipoint mode
d) no line feed or checksum characters are included
1. Read serial recognition character from EEPROM in point-to-point mode:

(Since "2A" is HEX-ASCII value of "*" in the table).
2. Read serial address from the RAM of the meter number "15 HEX" in the multipoint
mode:
