Ulises, Glenn had a good idea about getting the PDQComm which has your file transfer protocols built in. It will save you a great deal of work. In addition, check the size of your InBufferSize and OutBufferSize properties on your OCX.

My app sends and receives commands to/from a radio scanner device. I store incoming strings in a form property, then send the output with the 'THIS.OUTPUT' command as you are. In your command above, is DATA the information in the file? If so, then it may be too large for your buffer. Try sending a simple, short text string to the other computer and see if it is received.
