The following table gives the values for error code 1 that can be returned on the Open(PLU) Error Confirm message. Error code 2 is zero, except when error code 1 is 0x0821; in this case it contains the byte offset in the BIND where the BIND failed to match the BIND check table.
| Error code | Description |

| 0x0052 | SSCP connection no longer active. |
| 0x0821 | BIND checking failed: error code 2 gives byte offset in BIND at which the error occurred. |
