HEIDENHAIN ND 720 v.3 - Manual (Page 67)

Description of RS-232-C/V.24 commands:
The display unit supports the XON-XOFF protocol when
executing commands. As soon as the internal character
buffer (100 characters) is full, the display unit sends the
control character XOFF to the sender. After the buffer has
been executed, the display unit sends the control character
XON to the sender. Following that, it is ready to receive data
again.
Key is pressed (TXXXX commands)
The display unit acknowledges each identified key command
by sending the control character ACK (Acknowledge
Control-F). Following that, the key command becomes
effective.
The display unit responds to commands that cannot be
identified or to invalid commands by sending the control
character NAK (No acknowledge Control-U)
Output of model designation:
The type of display unit, software number and the date of
software release are output.
