I think you are spot-on with this suggestion Kozz - The problem here seems to relate more to the specifics of the FTP connection and network translation than the program code itself. I have discussed this aspect of FTP transfer previously in some detail in the node Re: Net::FTP Unexpected EOF.

While the node referenced above deals more specifically with the usage of Net::FTP (which I believe would offer a much cleaner and compact solution in this case), PASV behaviour as discussed in the above node can be initiated within a FTP session through the issuing of the command PASV prior to any commands which make use of the ftp-data connection (eg. LIST).

Using the code in question as a base ...

print FTP "PASS password\r\n";
sysread (FTP, $FormData, 1024);
print STDOUT "$FormData\n";

print FTP "PASV\r\n";
sysread (FTP, $FormData, 1024);

Just on a final note, you know that by introducing sysread in the manner that you have, you have also introduced some very nasty buffer dependencies in your code - This in itself could cause a number of headaches as your code is moved into production.
