 I find it easier to white a simple serial to memory routine
and then use SAVE to create the image files. One doesn't
have to worry about handshake since the program can run at
full speed. Since this is a true image, one can transfer
.HEX or .COM files without dealing with LOAD that is not
built into the command processor.
