How to put file to vsftpd server using FTPS sample

How to put file to vsftpd server using FTPS sample.

I want to put file to vsftpd server using FTPS sample of following URL.

developer.sierrawireless.com/Res … ample.aspx

data.txt file is created in the vsftpd server, but data of the contents are garbled, and the file size is 84byte.

If I specify the WIP_SSL_NEVER to parameters of wip_SSLInitOpts(), I can send the data.txt to the IIS server.
But, when I sent the data.txt to the vsftpd server, it was not send.

1.What is the cause that data cannot be sent to a vsftpd server?
2.Are there anyone who transmitted the file to the server of vsftpd using the FTPS sample?

My development environment is following.

Communication unit : AX8084NE
LSI of communication unit : SL8084T
Server OS : Fedora9
FTP mode : passive
