I think I would do it like this. Read the file as a binary file (avoids conversions the Read Text File can add on you) and send the data in chunks. Read the size of the data being sent each time data is sent. You can then do the comparison on each chunk. Repeat until the end of file error happens, some other error, or you fail. This setup also makes sure both ports are set up before any communication can occur.

I really like it... my solution worked also but this's more robust.

In LV 2013 the Clear Error vi cannot filter the error codes the way you did.. anyway using Filter Error Code it should work.
