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 and is then ready to receive data again.
Pressed key (TXXXX commands)
The display unit acknowledges each identified key command
by sending the control character ACK (Acknowledge Control-
F). Then 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 model of display unit, software number, and the date of
software release are transmitted.
