Note
· To suppress arbitrary call releases on DTR deactivation setting of AT&D0
is recommended. Refer to “AT&D Set circuit Data Terminal Ready (DTR)
function mode”, Chapter 2.34.
· If several AT commands are entered on the same line this command
needs to be the last one.
· Command setting is storable via AT&W, see Chapter 2.38.
· If enabled, DTR activation triggers a dial command (ATD) as though it
were entered by a TE. If in this situation characters are entered on the
same serial channel the ongoing dial command will be terminated (user
break).
