OFTP problem

Hi, I am having a problem with OFTP. I am using OFTP to transfer files from one unix server to another. I am able to receive any number of files at a time. But while sending, if the send directory is having more than three files, then first three files will be OFTPed and the remaining files will not be OFTPed.
I am getting an OFTP error 102 : Protocol violation.

I think somewhere we have to mention the number of files to be sent at a time. But I don't know where I have to go and change it.

If anyone knows please help me.

Thanks in advance.....

What is OFTP, Why dont you use simple FTP instead? I tried to google for OFTP, and it appeared to be some custom program. Please enlighten me.
