To summarize, the entire 18 ASCII character packet will be sent as follows, where
the start character, SOH = Ctrl-A = 01 hex is the first byte sent and the carriage
return = 0D hex is the last byte sent:

(Note that the spaces between bytes are shown for clarity only and are not actually
sent.)
The actual data is sent in serial binary format. Each 8-bit byte is framed with 1 start
and 1 stop bit. No parity bits are being sent or received. Therefore this data packet
is 180 bits long.
The data interface will receive this command and place it in a temporary memory
area. Before executing the command, several checks are made. If an illegal
condition is detected, the command will not be executed and an error message will
be sent back to the computer. The conditions that are checked are described in the
Error Responses section of this document.
If no errors are detected, the data interface will execute the command, and then send
a 2 byte Acknowledge Packet back to the computer.
The format of the Acknowledge Packet is:
A <CR>
where <CR> indicates the carriage return.
In ASCII coded hexadecimal:
41 0D
