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:
