File transfer with no flow control



I am trying to send serial data to an ftp site using the sample FTP routine that is supplied with Open AT 3.01, but my embedded device has no flow control lines available so I loose data when I send data, even at 9600 baud. Can anyone please show me how to modify the sample FTP code to provide some buffering? My file size is < 100 Kbytes.

Many thanks,

Paul Hutchinson.
