Command Description Effective
S211 =n [?] Ignore DTR . For applications or situations where
hardware control of the modem is not possible, the
modem can be configured to ignore DTR. When
Ignore DTR is enabled, the modem operates as if
the DTR signal is always asserted.
n=0 [default]: Use hardware DTR.
n=1: Ignore DTR.
n=3: Ignore DTR and assert DSR. This value is
deprecated, and it recommended to use
&S to
control the DSR instead. When this value is set to
3, &S will automatically be set to 0.

S221 =n [?] Connect Delay [n = 0 – 255]
n = number of seconds to delay the “CONNECT’
response upon establishing a TCP connection
OR
n = number of tenths of seconds to delay
outputting ENQ on the serial port after the
CONNECT when the ENQ feature is enabled [see
*ENQ]
Immediately
S300 =n [?] Set or query whether a private or public (network)
IP is to be used when the Host initiates a PPP
connection to the modem.
n = 0 [default]: Public (network) IP Mode: When
the Host initiates a PPP connection, the host will
be given the public IP that was obtained from the
OEM Modem. If the network issues a new IP, the
PPP connection will be closed (since the IP has
changed) and has to be re-initiated.
n = 1: Private IP Mode: When the Host initiates a
PPP connection, the host will be given the IP
address specified in S301. The modem will then
perform NAT-like address translation, which
shields the Host from network IP changes.
S301 =d.d.d.d [?] Set or query the private IP address that is to be
negotiated by the PPP connection if
S300 =1.
S302 =d.d.d.d [?] Set or query the IP address that can be used to
directly contact the modem once a PPP connection
is established. If this value is not specified,
192.168.13.31 will be used.
NOTE: This is not normally used nor needed by
user applications.
TCPS =n [?] TCP connection timeout (TCPT) units.
n = 0: TCPT specifies minutes.
n = 1: TCPT specifies seconds.
