Troubleshooting Host Connections

I can't connect to my host.

You may not be able to connect to the host for the following reasons:

• The host and transport settings you specified in the Session Setup dialog box are not being recognized by the Design Tool. Verify your settings are correct and try connecting again.
  
  
• If you see a blank screen after establishing a host connection, the problem may be that the host has sent a disconnect to the Design Tool. Some hosts do this if they don't recognize the terminal type you have selected. When the host sends a disconnect, the Design Tool displays the following message in red on the bottom of the terminal screen:
  
  Your connection to <host name> has been terminated.
  
  
• To solve this, select a different model ID in the Session Setup dialog box and try connecting again.
  
  
• The host may be unavailable temporarily or the network hardware may be malfunctioning. Check with your system administrator or try connecting again later.

I suspect there's a problem with my model when trying to connect to the host.

If you suspect a host problem could be associated with running the model itself, try deleting a login command list if present. This will allow you to see the individual steps involved in the sequence and may resolve any issues in timing associated with the command list.
