prefix AT and are terminated with <Enter>. Corrections in a command
line are done with <Backspace>. A command line has a maximum of
4O characters, the command line is automatically cancelled by longer

by reset or by leaving the AT command mode.
To enter the AT command mode during an active data connection you
