This field is used in two different protocols:
Entering a CoName will cause your Ggate session to select a specific CoName (Connection Name) entry in the Ggate DSA configuration file on the Ggate gateway. The CoName entry can can define all configuration parameters that otherwise would have to be entered in the Ggate options, including your terminal device type, and associate a printer session with your terminal device. Your Ggate administrator will supply you with a CoName if appropriate. Note that the Ggate options that follow in the host configuration menu allow you to supply the whole range of DSA and terminal parameters. If you have the required permissions these are used to complete or override the CoName entry. If you do not supply a CoName you must supply enough Ggate options to make the connection. The host application mailbox and the host node will always be needed.
Entering a resource name will select a specific configuration in the TNVIP server. The configuration can define all configuration parameters that otherwise would have to be entered manually, and can also define your terminal device type, and associate a printer session with your terminal device. Your TNVIP administrator will supply you with the name of a resource if appropriate.
