AT
Command
ATXn Accepted but ignored.
ATYn Accepted but ignored.
ATZn Accepted but ignored. (Soft Reset and restore Profile).
DCD Option. The Digi Device Server controls the DCD output in accor-
dance with the parameter supplied. The parameter value, if valid is written
to S21 bit 5.
AT&Cn
&C0 DCD remains ON at all times.
&C1 DCD follows the state of the connection
DTR Option. This command interprets the ON to OFF transition of the DTR
signal from the DTE in accordance with the parameter supplied. The param-
eter value, if valid, is written to S21 bits 3 and 4. Also see S25.
&D0 -DTR is ignored (assumed ON).
do not provide DSR.
&D1DTR drop is interpreted by the modem as if the asynchronous escape
AT&Dn
sequence had been entered. The modem returns to asynchronous com-
mand state without disconnecting.
&D2DTR drop causes the modem to hang up. Auto-answer is inhibited.
(Default.)
&D3DTR drop causes the modem to perform a soft reset as if the Z com-
mand were received. The &Y setting determines which profile is loaded.
Restore Factory Configuration (Profile)
The Device Server loads the factory default configuration (profile). The fac-
tory defaults are identified for each command and in the S-Register descrip-
AT&Fn
tions. A configuration (profile) consists of a subset of S-Registers.
&F0Restore factory configuration 0.
&F1Restore factory configuration 1.
AT&Jn Accepted but ignored.
AT&Gn Accepted but ignored.
AT&Jn Accepted but ignored.
Flow control. This command defines the DTE/DCE flow control mechanism.
The parameter value, if valid, is written to S39 bits 0, 1, and 2.
&K0 Disables flow control
&K3 Enables RTS/CTS flow control (Default)
AT&Kn
&K4 Enables XON/XOFF flow control
&K5 Enables transparent XON/XOFF flow control
&K6 Enables both RTS/CTS and XON/XOFF flow control.
AT&Ln Accepted but ignored.
