pscp? psftp? These are typically window's ports of SSH clients that come with PuTTy.
So you should probably google for PuTTy ... I only know about OpenSSH's scp and sftp.
scp [-pqrvBC46] [-F ssh_config] [-S program] [-P port] [-c cipher]
[-i identity_file] [-o ssh_option] [[user@]host1:]file1 [...]
... so if you want to scp to a sshd server listening on port 80 you could do this ...
scp -P80 myfile firstname.lastname@example.org
sftp is a bit different ...
sftp -oPort=80 dizzydorf.com
Be aware that 80 is typically the port httpd (like apache) use. You can check to see what is listening on port 80 with telnet.
$ telnet dizzyland.com 80
Connected to dizzyland.com.
Escape character is '^]'.
That means sshd is listen on port 80 on your remote system.
