Chapter 5 – AT Commands, S-Registers, and Result Codes

Multi-Tech Systems, Inc. SocketModem MT5600SMI Developer’s Guide 

38

Command:

&C

RLSD (DCD) Option

Description:

The modem controls the RLSD output in accordance with the parameter
supplied. The parameter value, if valid, is written to S21 bit 5.

Default:

1

Defined Values:

0 

RLSD remains ON at all times.

1 

RLSD follows the state of the carrier.

Result Codes:

OK
Otherwise ERROR

Command:

&D

DTR Option

Description:

Interprets the ON to OFF transition of the DTR signal from the DTE in
accordance with the parameter supplied. The parameter value, if valid, is
written to S21 bits 3 and 4. Also, see S25.

Default:

2

Defined Values:

&D0  DTR drop is interpreted according to the current &Q setting as

follows:
&Q0, &Q5, &Q6: DTR is ignored (assumed ON). Allows operation
with DTEs, which do not provide DTR.
Q1 DTR drop causes the modem to hang up. Auto-answer is not
affected.
&Q2, &Q3 DTR drop causes the modem to hang up. Auto-answer is
inhibited.

&D1  DTR drop is interpreted according to the current &Q setting as

follows:
&Q0, &Q1, &Q5, &Q6 DTR drop is interpreted by the modem as if
the asynchronous escape sequence had been entered. The modem
returns to asynchronous Command State without disconnecting.
&Q2, &Q3 DTR causes the modem to hang up Auto-answer is
inhibited.

&D2  DTR drop is interpreted according to the current &Q setting as

follows:
&Q0 through &Q6 drop caused the modem to hang up. Auto-answer
is inhibited.

&D3 DTR drop is interpreted according to the current &Q setting as

follows:
&Q0, &Q1, &Q5, &Q6 DTR drop causes the modem to perform a soft
reset as if the Z command were received. The &Y setting determines
which profile is loaded.
&Q2, &Q3 DTR drop causes the modem to hang up. Auto-answer is
inhibited.
If &Q5, &Q6, +FCLASS=1 or +FCLASS=2 is in effect, the action
taken is the same as for &Q0.

Command:

&K

Flow Control

Description:

Defines the DTE/DCE (terminal/modem) flow control mechanism. The
parameter value, if valid, is written to S39 bits 0, 1, and 2.

Default:

3 (for data modem modes)

Defined Values:

0 

Disables flow control.

3 

Enables RTS/CTS flow control.

4 

Enables XON/XOFF flow control.

5 

Enables transparent XON/XOFF flow control.

Note:

 Upon reset, both RTS/CTS and XON/XOFF flow control is enabled

for fax modem and voice modes.

Result Codes:

OK
Otherwise ERROR
