Posssible to execute FTP style site commands?

[snorkel]

Is it possible to execute commands once connected to a server via SFTP?
We need to send a file to a mainframe SFTP server and they have some odd propriatery
way to execute these commands which they call ls (which is stupid since ls is the directory list command)

For example I need to be able to do this(before I do a put):

sftp> ls /+mode=text

SFTP protocol does not support command transfer. For commands execution you can use the TScSSHShell component.
