Table 4-10: DART 300 Result Codes
Code Verbose DART 300 Meaning
0
OK Command executed without error.
1
CONNECT
Client Sessions – In SLIP and UDP this means a session is open and
the modem is in data state, but does not necessarily verify that the
modem is registered on the network. In TCP it indicates the session
is open and the destination is logically connected.
Server Sessions – The modem has opened the session and gone into
data state. The CONNECT message will be appended by the IP
address of the caller.
2
RING A connection to an accepted IP is requested.
3
NO CARRIER
The modem did not have an active CDPD connection, or a TCP
session was closed by the other terminal.
4
ERROR
Illegal command. Error in command line. Command line exceeds
buffer size. NVRAM failure.
S63
in the DART 200 contained an extended reason code, not
supported in the DART 300.
5
CONNECT
Connected with an active session. The modem transitions from
command state to data state.
6
PAD ERROR
An error has occurred in the packet service stack. The modem must
be reset.
The DART 200 uses this to mean NO DIALTONE – the modem
was not registered when the connection was attempted.
8
NO ANSWER
TCP service failed to complete the connection handshake.
The DART 200 uses this to mean NO ANSWER – the remote
modem was out of coverage or not registered (TCP only).
The DART 200 also supported code 7 to mean BUSY. This indicated that the remote modem was
busy, an invalid port was specified, or the server function was not active (TCP only).
