4.5. Result Codes
This table provides a numerical list of the result codes possible on the DART 300. DART 200 codes 9 and 10 are related to PIN use, which is not supported on the DART 300.
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).
