DART 300 Migration Guide Comparative AT Command Reference

Table 4-4: AT [*] Commands (continued)
Command DART 200 DART 300 Equivalent
*C
Compress SLIP Header
Controls SLIP mode header compression (V-J
compression) between the local host and the
DART 200 modem.
Compress SLIP Header
Not supported.
*E
Enable / Disable Network Operations
If PINs are required for network access, this
command enables and disables access to the
network.
Enable / Disable Network Operations
Not supported.
*G
Multicast Address Selection
Specifies whether the multicast NEI or the
modem’s active point-to-point NEI is passed to
the local host as the multicast data packet’s
destination address.
Consult the DART 300 User Guide for details
on multicast operation.
*K
Keep-Alive for TCP Sessions
Allows modems using TCP to time out, or
keep-alive a TCP session with no current
activity.
See the DART 200 User Guide for details.
Keep-Alive for TCP Sessions
The DART 300 supports a timeout for
gracefully closing both UDP and TCP sessions
based on no traffic in either direction. There is
no internal keep-alive “dummy” packet
support. See Section 3.2.3.1 above for more
detail.
*K0 = S30=0 (no timeout)
*K1-2 = not supported (unidirectional)
*K3 = S30=t (t = time equivalent to
DART 200 register S85)
Where the DART 200 would send and receive
keep-alive dummy packets for *K3, the
DART 300 requires no such packets and will
not discard dummy keep-alive data.
*L
Listening Port
Specifies the port number that the servers (TCP
or UDP) listen on for connection requests or
incoming data packets.
Listening Port
The DART 300 uses a register for this.
*M
MAS IP address for SLIP
Sets the IP Address of the local host (MAS)
connected to the DART’s serial port.
MAS IP address for SLIP
Not supported.
WirelessExpert will configure a Dial-up
Networking SLIP connection with the
modem’s NEI as the source IP address.
*P
PING
Issues ICMP Echo Requests to a Remote Host
and waits for a response.
PING
Not supported.
PINGs must be originated from the local host
using a SLIP or PPP connection.
*R
Automatic SLIP Mode
Controls whether or not the modem will
power-up to a SLIP data state rather than the
AT command state.
Automatic SLIP Mode
Not supported.
