This is the login identification required by the host operating system, not to be confused with the host application, which may have a separate login.
If the login name or password is set to "[init]", ATE will prompt separately for the login information prior to the first connection, and will then replace "[init]" with the information entered. This is useful when the person setting up the configuration is not the one actually using it. Also see Username, Password on the FTP tab, and server name on the Transport tab.
In the case of ATSD, there is no standard user login (name/password) as there is with UNIX telnet/ssh servers. So the interpretation of the login name and password fields is a bit less concrete, and depends on how the host application handles new connections. Starting with ATE 1217.2, the login name/password fields, if not blank, will be send in response to the first two application prompts. If those two first host application prompts are in fact for a user name and password, then use those fields in the same way as you would for UNIX. If the application only prompts for a password, then leave the login name field blank. If it prompts for neither (or for earlier versions of ATE), just leave those two fields blank put any additional startup text in the field labeled for that purpose.
Note: in some versions of ATE, a blank name or password field will cause it to display a login dialog prompting for the credentials before actually attempting the connection. To stifle such a dialog, you can enter a single tilde (~) in the otherwise blank name and/or password fields. The character is not sent to the server; it is only used as a flag to bypass the display of an explicit login dialog.
