to alibi-memory or physical printer.
Example: 'R100'
Setting

4.5.3.4. Commands for Data Protocol
PROTOK
Command No 38h
Parameters: Acknowledge protocol
This command is for matching the acknowledge protocol with the requirements of the
other station. The relevant setup parameter will be overwritten. The command is followed
by an ASCII character selecting the protocol. The following modes can be set:
'0'
standard protocol, acknowledge characters ACK and NAK are transmitted
according to DIN 66019.
'1'
A810 will not transmit ACK and NAK.
'2'
A810 will transmit ACK and NAK enclosed in a block frame made up of STX and
ETX.
The command takes effect immediately, so command PROTOK is acknowledged already
by the newly set protocol. If needed at all, this command should always open the
exchange of data.
ADDRESS
Command No 39h
Parameter: device address
The interconnection of several terminals in a TTY ring or on an RS485 BUS requires that
exactly one device is addressed at any time. Immediately after power-on the device
having the address '0' is active. Command ADDRESS is for selecting the device the
address of which is the parameter transmitted whereas all the other devices in the ring
are disabled.
Example:
'95'
enable device with address 5
LINES
Command No 3Ah
Parameter: block structure
The command LINES determines the structure of a data block by defining its header and
end. The relevant parameters in the Set-up will be overwritten. This parameter can be
used to match the data protocol of the terminal with the conventions of the program
running on the computer. The following modes can be set:
Parameter
block header
end of block
'0' STX
ETX
'1' STX
CR
ETX
'2' STX
LF
ETX
'3' STX
CR
LF
ETX
'4'
'5'
CR
'6'
LF
'7'
CR
LF
When a protocol approved for calibration is used, only parameters '0' to '3' are permitted
since the protocol requires characters STX and ETX.
