To establish an FTP connection to your mainframe, determine this information:
User ID.
Password.
Mainframe host name.
Control port number – the listener port used by your mainframe FTP server, usually 21.
TCP address space name.
Volume serial number or unit – specify either a volume serial number (VOL=SER) and unit assignment for FTP to use, or allow FTP to use default values.
Log path name – indicates where FTP log information will be written.
