USING CONTROL KEY SEQUENCES TO SEND COMMANDS

Commands composed of a single control code may be sent using a control key sequence corresponding to the assigned data byte.

Where control key sequence formats are shown in this manual, CTRL represents the control key on the computer keyboard, not individual characters to be typed. Control key sequences (for example, CTRL A) are sent by pressing the control key (CTRL) together with the key for the specified character. If CTRL does not appear before a character within the sequence, the key for that character is pressed alone.

The table below shows ASCII control codes assigned to data bytes 0 through 31 (decimal) and the corresponding control key sequence.
