6.1 General
The command set described below defines the transfer of data on the serial interface.
The commands consist of a command code and optionally of a parameter value. Commands
are terminated by the control character <CR> (13h). The control character serves as com-
mand line terminator.
Command codes and parameters, that means all letters and numerical values, are princi-
pally transmitted as a sequence of ASCII characters (the value 255 (decimal) consequently
as 32H, 35H, 35H; the command RST as 52H, 53H, 54H).
The protocol format is as follows
command <SP> parameter <CR>
The space character <SP> separates commands from parameters and the <CR> character
acts as command line terminator.
For commands without parameter values (e.g. GT ) the <SP> character and parameter val-
ues are omitted. The command line is as short as this:
command <CR>.
Generally, every input terminated by <CR> is acknowledged by the reader. The following
response protocols are different:
