How do I configure these settings in WINSCP

I used Scriptftp before but am now forced to use a corporate standard. How do I enforce the following using WINSCP v4.3.4 build 1428
SETPROTOCOL(FTPS_EXPLICIT_ENCRYPT_DATA)
SETPORT(2121)
SETPASSIVE(DISABLED)

Please read documentation:
https://winscp.net/eng/docs/scriptcommand_open

open ftp://username:password@hostname:2121 -explicitssl -passive=off

Alternatively use -explicittls.
