P.22
A2.2.2.7 &D
[<value>]
- DTR Behavior
This parameter determines how the modem responds when the Data Terminal Ready (DTR) input is changed
from the ON to the OFF condition during online data state.
Defined Values
<value> Decimal number corresponding to the selected option.
0
Modem ignores DTR.
1
Upon an on-to-off transition of DTR, the modem enters online command state and issues an OK result
code; the call remains connected.
2
Upon an on-to-off transition of DTR, the modem instructs the underlying modem to perform an orderly
cleardown of the call. The disposition of any data in the modem pending transmission to the remote
modem is controlled by the +ETBM parameter; otherwise, this data is sent before the call is cleared,
unless the remote modem clears the call first (in which case pending data is discarded). The modem
disconnects from the line. Automatic answer is disabled while DTR remains off.
A2.2.2.8 &K
[<value>]
- Flow Control
This command defines the DTE/DCE (terminal/modem) flow control mechanism.
Defined Values
<value> Decimal number corresponding to the selected option.
0
Disables flow control.
3
Enables RTS/CTS flow control. (Default for data modem modes.)
4
Enables XON/XOFF flow control.
5
Included for compatibility only and has no effect other than returning an OK result code.
6
Included for compatibility only and has no effect other than returning an OK result code.
A2.2.2.9 &M
[<mode>]
- Asynchronous/Synchronous Mode Selection
This command is included for compatibility only and has no effect other than returning a result code. The only
valid values are 0-3.
A2.2.2.10 &Q
[<mode>]
- Sync/Async Mode
This command determines the DTR operating mode. (Also, see \N.)
NOTE:
When the &Q0 is issued to select the mode, the subsequent connect message will report the DCE speed
regardless of the W command and S95 settings.
Defined Values
<mode > Decimal number corresponding to the selected mode:
0
Selects asynchronous operation in normal mode (speed buffering)
1
Selects asynchronous operation in normal mode (speed buffering)
2
Selects asynchronous operation in normal mode (speed buffering)
3
Selects asynchronous operation in normal mode (speed buffering)
6
Selects asynchronous operation in normal mode (speed buffering).
