Troubleshooting Checklist

Is the server device operational? For a printer, check to be sure that it is powered on, is not out of paper, and is on-line.

Can the DTC or other terminal server port be accessed through the LAN? Ping the IP address of the server. If successful, it means that the network data path is working correctly.

Are there any configuration mismatches between the dp file on the host and the DTC or other server? If so, correct them and try again.

In the dp file, the following parameters should match the DTC or non-DTC server port settings:

DTC or server IP address, DTC or server node name, board/port numbers (for DTCs only), and the port's TCP address.

Are the device port characteristics like direct connect or modem, flow control, baud rate and parity correct? If not, then correct them, since they do impact the connection, especially one with modems.

If the problem continues, go to the following sections, based on whether it is an incoming or an outgoing connection.

If the problem still cannot be resolved, collect the diagnostic information listed at the end of this chapter, and call your Hewlett Packard support engineer.
