Been a long time since I played with serial comms, but that'd be my first attempt.

Second attempt would be to make a full serial connection to another machine (port on the same machine?) and use "ckermit" to transfer a file.

Thanks Stephen.

Your first attempt was what I was trying to accomplish. The second attempt may be what I next try.
