Syntax: open [<servername> [<username> [<password> [<account>]]]]
The OPEN command connects to the FTP server and attempts to log in using the server name, username, and password specified. For case-sensitive servers, be sure to use the appropriate case when typing parameter values. If no parameters are specified with the OPEN command, the user is prompted for login information.
When only one parameter is present, it must be <servername>. If you add a second parameter it must be <username>. If you use three parameters, the third must be <password>.
Note: If you use a passthrough server to log into FTP servers, use the PASSTHRU command to open a server connection.
This command opens an anonymous connection to the FTP server, supplying an e-mail address for the password:
OPEN ftp.acme.com anonymous email@example.com
The following command opens a connection to the Headquarters FTP server for user Jackie. A password parameter wasn't specified, so the user will be prompted to enter a password during the login process.
