Description of commands
The TCP connecting circuit processes the commands that are sent depending on the
antenna that is specified.
This means that a command may be sent for antenna 0
or
a command may be sent
for antenna 1.
The command can be sent as two ASCII characters, as a decimal number in ASCII
format, or as a hexadecimally coded decimal number.
This will be illustrated using the command "Read data carrier, single read" as an ex-
ample:
In ASCII format, the command is ’SR ’. As a decimal number, it is ’16’.
The hex values to be transferred are represented in lines 1 and 2 in parentheses.
