&D - Data Terminal Ready (DTR) Control SELINT 2
then AT&D1 has the same effect as AT&D2.
Note: if AT&D2 has been issued and the DTR has been tied Low,
autoanswering is inhibited and it is possible to answer only issuing
command ATA.
Note: if parameter is omitted, the command has the same behaviour of
AT&D0
Reference V25ter
3.5.3.2.8 Standard Flow Control - \Q
\Q - Standard Flow Control SELINT 0 / 1 / 2
AT\Q[<n>] Set command controls the RS232 flow control behaviour.
Parameter:
<n>
0 - no flow control
1 - software bi-directional with filtering (XON/XOFF)
2 - hardware mono-directional flow control (only CTS active)
3 - hardware bi-directional flow control (both RTS/CTS active) (factory
default)
Note: if parameter is omitted, the command has the same behaviour as
AT\Q0
Note: Hardware flow control (AT\Q3) is not active in command mode.
Note: \Q’s settings are functionally a subset of &K’s ones.
