3.9.2 Serial Transmission Data Format
The data is transmitted in ASCII as BCD values and can be presented with any terminal
program (TERMINAL.EXE under Windows for example). The following control characters,
among others, from the ASCII character set are used in the construction of the data string:
$20 = Space
$0D = CR (carriage return)
$0A = LF (line feed)
$02 = STX (start of text)
$03 = ETX (end of text)
Status values are to be evaluated separately (see data string construction).
